How to create NanoBSD iso image to install NanoBSD on vmware machine?
Dear Friends, I am new to Nanobsd and trying to create an iso image which can be installed on vmware machine. I created an iso image using the disk image (/usr/obj/nanobsd.full/_.disk.image) generated according to steps given in NanoBSD How To http://www.freebsd.org/doc/en/articles/nanobsd/howto.html . VM could boot up with this ISO image, but I got an error as below before I could get OS installation prompt: mount: /dev/ad0s3: No such file or directory mount -o ro /dev/ad0s3 /conf/default/etc failed: droppnig into /bin/sh Cannot read termcap database; using dumb terminal settings. # do I need to use different commands or options to create iso image while using nanobsd.sh script? Please help. Many thanks in advance for your help and time.

Task bar missed when creating PC-BSD release 9.1 64 bit VM in VMware Workstation Version 98.02 build-1031769
Hi, I am trying to create a virtual machine of PC-BSD release 9.1 64 bit in VMware Workstation Version 98.02 build-1031769 based on PCBSD9.1-x64-DVD.iso downloaded from ftp://mirrors.isc.org/pub/pcbsd/9.1/amd64/PCBSD9.1-x64-DVD.iso in Windows 7 64 bits system. The screen resolution is 1280x1024, if I chose Yes in Confirm Resolution window to keep the autodetec, then after the whole creation process finished, and login in as a created user, the task doesn't appear in the bottom below the desktop. If I powered off the VM, and changed the Display setting to Specificy monitor settings with Maximum resolution set to 1024 x 768 by Virtual Machine Settings in Workstation, and repower on the VM, then the task bar appears on the bottom below desktop. What is the issue? Did I miss anything during the VM creation? Thanks. David , and setup network configuration and installed Firefox 20.0 by AppCafe, and configured the network setting in Preference-Advanced of Firefox, and I could access Internet. Now I need to build my own customized kernel, but there is no src subdirectory in /usr, so here is my question: 1.Is there any way to install kernel source when I create the virtual machine from PCBSD9.1-x64-DVD.iso ? 2.Any BKM to get the kernel source after the Virtual Machine already created as my case now? Thanks!

VMware tools for FreeBSD
Hi, I am running an ESXi 5.1 VMware server, with one FreeBSD (8.3) guest. I am trying to figure how to install the VMware tools: - the linux one are working, but I woul prefere a more native FreeBSD - should I install /usr/ports/emulators/vmware-guest6d ? It fails with not finding vmware-guestd. - should I install /usr/ports/emulators/vmware-tools6 ? It seems it needs vmware-guest6d as a prerequisite. What else? All documentation I find on the web refers to a VMwareTools for FreeBSD, that I could not locate. Help please.

Re: VMware tools for FreeBSD
If this is a production server operation VMWare will *only* support you running their list of supported FreeBSD versions and their official VMWare Tools. This means you'll often be left behind several releases with the most recent available being completely abandoned by the FreeBSD project. It's a sad situation that they call this supported. If you really don't have any concerns about that what you want is emulators/open-vm-tools or emulators/open-vm-tools-nox11 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

FreeBSD on VMware ESXi with PCI Pass Through enabled
Just curious if anyone has any good recommendations of settings for running FreeBSD under VMware ESXi 5.1 with PCI(e) pass through enabled. I have been doing some initial testing with a new motherboard processor and RAM. That I am hoping to be able to run 3 Servers on. The intended virtual machines for the setup. 1.) A FreeBSD system to run Bacula, which will require PCI pass through for an eSATA drive dock so backups volumes can be Rotated. 2.) A FreeBSD system to host my web/email server, no pass through required. 3.) A FreeNAS box host SMB shares and iSCSI, will use a PCI pass through to allow direct access to 4 Hard drives, attached to a separate SATA controller. Current Hardware Information: eSATA Controller for backups: Koutech IO-PESA111 PCI Express SATA II (3.0Gb/s) - uses Silicon Image 3132 Chipset System Board: ASUS F2A85-M PRO FM2 AMD A85X (Hudson D4) CPU: AMD A10-5800K Trinity 3.8GHz (4.2GHz Turbo) Socket FM2 100W Quad-Core Desktop APU (CPU + GPU) RAM: CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) I still need to add an additional controller SATA controller for the FreeNAS VM, but so far testing with a new machine built for the Bacula install has only been consistently able to trigger a complete core dump and crash of the ESXi host machine, sometimes at boot of the VM with PCI pass through, sometimes not until a load has been applied to the external hard drive on the Pass through SATA controller. I have tried the following things to fix this that I have come across while searching for help. Added the following to /boot/loader.conf: hw.pci.enable_msi=0 hw.pci.enable_msix=0 Added the following to the Vmware Virtual Machine Configuration: pciPassthru0.msiEnabled = FALSE -- Thanks, Dean E.

Re: FreeBSD as VMWare guest / disk resizing
You'll of course need to boot from another medium to do this. That's my main question - can a larger disk be detected *without* a reboot. On FreeBSD instances running within VMWare I have been able to add new disks without a reboot but, as I described below, have not found a way to get the operating system to detect a larger *existing* disk without a reboot. VMWare allows you to resize a disk on the fly. Obviously I'm only interested in the grow the disk scenario :-) I'm beginning to think a reboot is necessary, which is surprising!

Re: FreeBSD as VMWare guest / disk resizing
It can be done but it's not easy and not pretty. You'll have to rewrite the partition scheme to grow *only* the last partition and then use growfs on the last partition to zero the new inodes within its newly defined range. You'll of course need to boot from another medium to do this. I usually use DruidBSD for this: DruidBSD-1.0b1.iso (a tiny 23.5MB ISO that you can write to thumb disk with dd or burn to cd; either works fine) Boot from it and use the tools like disklabel -e /dev/yourdisk But… be extremely careful and do your mathematics! I know this isn't a complete step-by-step guide, but I wanted to get the answer out there that this is possible and it's a known quantity, but it can be dangerous if you get the math wrong when editing the disklabel positions, for example. If you can get that part right, the rest is easy (growfs). -- Devin On Dec 17, 2012, at 4:15 PM, Luke Bakken wrote: Hello everyone - I'm looking for a way to get FreeBSD 8 / 9 to detect that an already existing disk has grown.

Re: Please help me diagnose this crazy VMWare/FreeBSD 8.x crash
Hi guys I'm excitedly posting this from my phone. Good news for you guys, bad news for us -- we were building HA storage on vmware for a client and can now replicate the crash on demand. I'll be posting details when I get home to my PC tonight, but this hopefully is enough to replicate the crash for any curious followers: ESXi 5 9 or 9-STABLE HAST 1 cpu is fine 1GB of ram UFS SUJ on HAST device No special loader.conf, sysctl, etc No need for VMWare tools Run Bonnie++ on the HAST device We can get the crash to happen on the first run of bonnie++ right now. I'll post the exact specs and precise command run in the PR. We found an old post from 2004 when we looked up the process state obtained from CTRL+T -- flswai -- which describes the symptoms nearly perfectly. http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2004-02/0250.html Hopefully this gets us closer to a fix... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Re: Please help me diagnose this crazy VMWare/FreeBSD 8.x crash
So when this hang happens, there never is a real panic. It just sits in a state which I describe as like being in a deadlock. How would I go about getting a crashdump if it never panics? Is it possible to do the dump over a network or something because I don't believe it can write through the controller at all. Also, thank you for the KTR_SCHED tip. This is the type of info I was looking for. Unfortunately I've only ever seen this crash once on a kernel with debugging enabled. The machine which is currently prepared to do this work used to crash a few times a week and now it has 70 days uptime... however, it is an example of a machine with mpt0 and em0 sharing an IRQ so I might be able to trigger it using Dane's method. $ vmstat -i interrupt total rate irq1: atkbd0 392 0 irq6: fdc0 9 0 irq14: ata0 34 0 irq18: em0 mpt0 1189748491218 cpu0: timer 2174263198400 Total 3364012124619 I'm doing my best to get you guys the info you need, but this is one heck of a Heisenbug... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

You can break into ddb and run 'call doadump'. It should use polled IO, so there is a slight chance of it working. Also, thank you for the KTR_SCHED tip. This is the type of info I was looking for.

Re: Please help me diagnose this crazy VMWare/FreeBSD 8.x crash
Hi, can you please, -please- file a PR? And place all of the above information in it so we don't lose it? If this is indeed the problem then I really think we should root cause why the driver and/or interrupt handling code is getting angry with the shared interrupt. I'd also appreciate it if you and the other people who can reproduce this could work with the em/mpt driver people and root cause why this is going. I think having FreeBSD on vmware work stable out of the box without these kinds of tweaks is the way to go - who knows what else is lurking here.. I'm very very glad you've persisted with this and if I had them, I'd send you a FreeBSD persistent bug reporter! t-shirt.

OK guys I've been talking with another user who can recreate this crash and the last bit of information we've learned seems to be leaning towards interrupts/IRQ issues like someone (bz@ perhaps?) suggested. I'm still trying to test this myself, but the other user was able to recreate my crash pretty much on demand. The fix was to not use the first NIC in the VM because it will always share an IRQ with mpt0. Once mpt0 is on its own the crash does not seem to be reproducible anymore.

[snip] I am not anywhere near your level in this subject area. My understanding is limited and do not have the in-depth experience. However, please allow me to possibly add an idea or two. I am shakedown testing FreeBSD 9 in a VirtualBox VM - so there is definitely a degree of 'apples vs oranges' present. VirtualBox (as I am using it) is a userland app and not a bare-metal hypervisor. When I set up the VM I chose to use the synthetic SAS controller as that would best represent actual server hardware in my workplace, along with the corresponding mpt driver in the FreeBSD 9 guest. Please note some of the following for comparative purposes only: [...] Event timer LAPIC quality 400 ACPI APIC Table: VBOX VBOXAPIC FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs FreeBSD/SMP: 1 package(s) x 2 core(s) cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 ioapic0 Version 1.1 irqs 0-23 on motherboard kbd1 at kbdmux0 acpi0: VBOX VBOXXSDT on motherboard acpi0: Power Button (fixed) acpi0: Sleep Button (fixed) Timecounter HPET frequency 14318180 Hz quality 950 Timecounter ACPI-fast frequency 3579545 Hz quality 900 acpi_timer0: 32-bit timer at 3.579545MHz port 0x4008-0x400b on acpi0 [...] em0: Intel(R) PRO/1000 Legacy Network Connection 1.0.3 port 0xd000-0xd007 mem 0xf000-0xf001 irq 19 at device 3.0 on pci0 [...] mpt0: LSILogic SAS/SATA Adapter port 0xd100-0xd1ff mem 0xf082-0xf083,0xf084-0xf085 irq 22 at device 22.0 on pci0 mpt0: MPI Version=1.5.0.0 [...] The em0 is the first Intel NIC in Vbox and notice how it and mpt0 come up with distinctly different IRQs. A sysctl -a |grep mpt returns this: device mpt kern.sched.preemption: 1 kern.sched.preempt_thresh: 80 dev.mpt.0.%desc: LSILogic SAS/SATA Adapter dev.mpt.0.%driver: mpt dev.mpt.0.%location: slot=22 function=0 dev.mpt.0.%pnpinfo: vendor=0x1000 device=0x0054 subvendor=0x1000 subdevice=0x8000 class=0x01 dev.mpt.0.%parent: pci0 dev.mpt.0.debug: 3 dev.mpt.0.role: 1 Very curious how 'irq 22 at device 22.0' and 'dev.mpt.0.%location: slot=22' all match with a '22'. The obvious thing here is we are comparing a userland Vbox guest to a VMWare hypervisor. From what little I know concerning any of this, to me it sounds vaguely like an APIC, LAPIC, and IO/APIC bug. There are known bugs wrt to BIOS setting up IRQ routing incorrectly, and/or providing incorrect ACPI and/or IMS tables to operating systems. The parallel in this case would be the logical or synthetic so-called BIOS that the VMWare hypervisor presents to the FreeBSD guest at guest boot time. In this case the truest fix for the problem would fall to VMWare, e.g. if the hypervisor is setting up tables in such a way as to create the shared IRQ problem in the first place. If my idea/theory/potential hypothesis has any merit. I do not understand why any of this would be different depending upon which guest is installed, but I also know absolutely nothing about VMWare hypervisor internals. Is there any other way we can make mpt0 get its own dedicated IRQ without having to do this? The problem is that it causes us to have to make rc.conf changes, pf.conf changes, and who knows what other software could be on these machines that is trying to bind to a specific NIC... Very possibly Andrew's device.hints is probably your best shot at a workaround. Wish you the best of luck in any case. You have done quite a job in researching this problem even to arrive at this point. Thank-you for that, and for sharing it with the community.

Re: Please help me diagnose this crazy VMWare/FreeBSD 8.x crash
Quick update: I have received word last night that this crash has been consistently happening to someone on FreeBSD 9 and they're looking for more ideas. I changed the following 41 days ago: - Video memory to auto if it wasn't already - SCSI controller changed from LSI Logic Parallel to LSI Logic SAS It uses the same driver (da) but so far has been holding steady for us. As far as the video memory -- many of our servers somehow had video memory set to 1MB which seemed strange; newer builds of FreeBSD on ESXi do not show this option. Perhaps there was a build of ESXi in the past that had a different setting for video memory when you selected FreeBSD? Another change people might want to do as suggested to us by VMWare Support: - Change CPU/MMU Virtualization to the bottom option -- Use Intel VTx/AMD-V for instruction set virtualization and Intel EPT / AMD RVI for MMU virtualization Supposedly there are autodetection issues here with some OSes -- they named some BSDs and Netware. I'll provide further updates if anything changes, but this seems to be working well so far. We won't begin to trust it until we can hit at least 100 days of uptime, though. Unfortunately I was hoping to upgrade these servers to 8.3 before then... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

We're trying to figure out any commonalities that might exist; these may serve to help shed light on where the problem lies. The interesting thing is that I took it and looked at it and came to a conclusion that might have been wrong, though I think the trail of reasoning I used was itself reasonable, given my exceedingly small (one example of problem) sample size. Mark's able to actually *reproduce* the problem on separate installs and with circumstances that are at least somewhat different than what my theory involved, though it is not quite possible to rule out some sort of corruption. Since I have to *assume* that many sites run some sort of FreeBSD on their VMware gear, given that VMware actually lists it as a supported version and VMware generally does things for profit, I am still kind of of the opinion that this is some sort of corruption bug, one that I triggered inadvertently, but one that Mark's environment reproduces rather more frequently. That just seems so unlikely, but more unlikely things have come to pass, so I'm holding onto it as my working theory ;-) I still plan to try to recover my broken VM from backups at some point if time permits.

And since both the poster and I made it clear that this doesn't seem to be a case of it fails reliably on a machine of your choosing, just installing random other versions and hoping that it's going to cause a fail ... well, let's just say that doesn't make a whole lot of sense. Or at least it's a recipe for a hell of a lot of busywork, busywork not guaranteed to return any sort of useful result. What you suggest is a fine solution for My ASUS Sempron box fails when I do X! -- in such a case, Try a different version of FreeBSD makes lots of sense. The problem is, in a virtualization environment, theoretically the virtual hosts are all the same sort of hardware (modulo any specific configuration changes of course), so when someone presents a problem that afflicts only a percentage of their VM's, it is important to keep in mind that you are not interacting with physical hardware, and that reinstalling an OS on a problem VM...? Well, let's just say I like real hardware better for many reasons. In the meantime, it's unrealistic to tell people to use supported releases, to wait fifteen months between releases, and then to criticize people complaining about problems with a supported release for using old code. ...

Try disabling msi in /boot/loader.conf like this: hw.pci.enable_msi=0 hw.pci.enable_msix=0 At least if it makes no difference maybe this will exclude it from being a 'possible'.

Hi, * have you filed a PR? * is the crash easily reproducable? * are you able to boot some ramdisk-only FreeBSD-8.2 images (eg create a ramdisk image using nanobsd?) and do some stress testing inside that? It sounds like you've established it's a storage issue, or at least interrupt handling for storage issue. So I'd definitely try the ramdisk-only boot and thrash it using lighttpd/httperf or something. If that survives fine, I'd look at trying to establish whether there's something wrong in the disk driver(s) freebsd is using. I'm not that cluey on ESXi, but there may be some PIC/APIC/ACPI change between 7.x and 8.0 which has caused this to surface. We've seen this. Or something that seems really like it. We run dozens of FreeBSD VM's, many of which are 8.mumble. We have a scripted build environment dating back many years, so generally servers come out in a fairly reproducible form. After several months of smooth running, we had need to shuffle some things around, and migrated some servers to a different datastore. Suddenly, one particular VM, our corp Jabber server, started randomly disconnecting people every morning. Some inspection showed that the machine was running, but disk I/O in the VM was freezing up. Subsequent inspection suggested that it was happening during the periodic daily, though we never managed to get it to happen by manually forcing periodic daily, so that's only a theory. Given that several times it appeared that one of the find commands was running, I was guessing that something in the thin provisioned disk image for the system had gone bad, but reading the entire disk with dd didn't cause a hang, running the periodic daily by hand didn't cause a hang, etc. Migrating the VM to a different host and datastore did not fix the issue. Migrating the VM from an Opteron to a Xeon host with all the latest ESXi 4 patches also didn't make any difference. Migrating the disk image from thin to full seemed to fix it, but I only gave it a day or two, then decided there were other good reasons to reload the VM, so I nuked the VM, which, of course, fixed it. In the meantime, a dozen other similar VM's alongside it run just fine. My conclusion was that it was something specific that had gone awry in the virtual machine, probably in the disk image, but I could not identify it without significant digging that I had no particular reason or inclination to do; since it appeared to be a VMware problem, the reload it and be done with it seemed the quickest path to resolution. That having been said, if anyone has any brilliant ideas about what would constitute useful further steps to isolate this, I can look at recovering the faulty VM from backup and seeing if it still exhibits the problem. ...

We can have that discussion if you don't understand that, drop me a note off- list and I'll be happy to explain it. Otherwise, you've told him to run a newer version, of which NONE IS AVAILABLE, unless you're thinking 9.0, but FreeBSD has a rather catastrophic history of point zero releases, and most clueful admins won't run those in production without carefully measuring the risks and benefits. So you've basically told him to run a newer version without any such version being realistically available. WTF? You want people not to use releases that came out over a year ago?

And it's not so much a crash as it is a disk I/O hang. The fact that it was happening regularly to that one VM, while a bunch of other similar VM's were running alongside it without any incident, along with the problem moving with the VM as it is moved from host to host and from Opteron to Xeon, strongly points at something being wrong with the VM itself. Our systems are built mostly by script; I rebuilt the VM a few months ago and the problem vanished. The rebuilt system should have been virtually identical to the original. I never actually compared them though. My working theory was that something bad had happened to the VM during a migration from one datastore to another. We have a really slow-writing iSCSI server that it had been migrated onto for a little bit, which was where the problem first appeared, I believe. At first I thought it was the nightly cron jobs just exceeding the iSCSI server's capacity to cope, so we migrated the VM onto a host with local datastores, and it remained broken thereafter. So my conclusion was that it seemed likely that somehow VMware's thin provisioned disk image had gotten fouled up, and under some unknown use case, it could be teased into locking up further I/O on the VM. I wasn't able to prove it. I tried a read-dd of the entire disk - passed, flying. I tried several things to duplicate the nightly periodic tasks where it seemed so prone to locking up. They all ran fine. But if I left the machine run, it'd do it again eventually. I explained it at the time to one of my VMware friends: But here's where it gets weird. Three times, now, one VM - our Jabber server - has gone wonky in the wee early AM hours. Disk I/O on the VM just locks up. You can type at the console until it does I/O, so you can put in root at the login: prompt but never get a pw prompt. My systems all run top from /etc/ttys and I can see that a whole bunch of processes are stopped in getblk. It's like the iSCSI disk has gone away, except it hasn't, since the other VM's are all happily churning away, on the same datastore, on the same VMware host. http://www.sol.net/tmp/freebsd/freebsd-esxi-lockup.gif Now it's *possible* that the problem actually happens after the 3AM cron run (note slight CPU/memory drop) but the Jabber implosion actually happens around 0530, see drop in memory%. But the root problem at the VM level seems to be that disk I/O has frozen. I can't tell for sure when that happens. All three instances are similar to this. I can't explain this or figure out how to debug it. Since it's locked up right now, thought I'd ping you for ideas before resetting it. Now that was actually before we migrated it back to local datastore, but when we did, the problem remained, suggesting that whatever has happened to the VM, it is contained within the VM's vmdk or other files. ...

Re: Please help me diagnose this crazy VMWare/FreeBSD 8.x crash
This sounds just like a race condition that happens under Windows 7 on this laptop. The race condition, as far as I can tell involves heavy disk access and heavy network access, and usually leaves the drive light on, while all activity monitors (alldisk, allcpu, allnetwork) are still active, although on this laptop disk takes priority, and network slows to a crawl. occasionally, the mouse will stop working, along with everything else, but usually not. keyboard is lower priority, and doesn't do anything. You might want to check with mickeysoft, this might just be their problem. This sounds so freaking similar to the issue I get, and I think it's a race condition (shared interrupts??). This laptop is a Compaq Presario C300 series, with the 945GM chipset and a T7600 Core2 Duo CPU, with 3G of RAM. Mark Felder wrote: Alright guys, I'm at the end of my rope here.

They claim it's not a VMWare issue. They can't identify what the heck happens. We had a glimmer of hope with ESXi 5.0 fixing it because we never saw any crashes in the handful of deployments, but our dreams were crushed today -- two days before an outage to begin migration to ESXi 5.0 -- when a customer's ESXi 5.0 server and FreeBSD 8.2 guest crashed. Crash Details: The keyboard/mouse usually stops responding for input on the console; normally we can't type in a username or password. However, we can switch VTs. If there's a shell on the console and we can type, we can only run things in memory. Any time we try to access the disk it will hang indefinitely. The server still has network access. We can ping it without issue. SSH of course kicks you out because it can't do any I/O. If we were to serve a lightweight http server off a memory backed filesystem I'm confident it would run just fine as long as it wasn't logging or anything. On ESXi you see that there is a CPU spike of 100% that goes on indefinitely. No idea what the FreeBSD OS itself thinks it is doing because we can't run top during the crash. This crash can affect a server and happen multiple times a week. It can also not show up for 180 days or more. But it does happen. The server can be 100% idle and crash. We have servers that do more I/O than the ones that crash could ever attempt to do and these don't crash at all. Completely inexplicable. Things we've looked into: Nothing about the installed software matters. We've tried cross referencing the crashed servers by the programs they run but the base OS is the only common denominator due to the wide variety of servers it has affected. Storage doesn't matter. We've tried different iSCSI SANs, we've tried different switches, we've tried local datastores on the ESXi servers themselves. HP servers, Dell servers -- doesn't seem to matter either. (All with latest firmwares, BIOSes, etc) VMWare gave us a ton of debugging tasks, and we've given them gigabytes of debugging info and data; they can't find anything. VMWare tools -- with, without, using open-vm-tools makes no difference. I think we've done a fair job ruling out VMWare.

Alright guys, I'm at the end of my rope here. For those that
haven't seen my previous emails here's the (not so) quick breakdown:
Overview:
FreeBSD ?? - 7.4 never crash
FreeBSD 8.0 - 8.2 crashes
FreeBSD 8-STABLE, 8.3, and 9.0 are untested (Sorry, not possible in
our production at this time, and we were hoping we could base some
stuff on 8.3 for long term stability...)
ESXi: Confirmed ESXi 4.0 - 5.0 has this problem. Haven't tested on
others.
History:
Over the course of the last 2 years we've been banging our heads on
the wall. VMWare is done debugging this. They claim it's not a
VMWare issue. They can't identify what the heck happens. We had a
glimmer of hope with ESXi 5.0 fixing it because we never saw any
crashes in the handful of deployments, but our dreams were crushed
today -- two days before an outage to begin migration to ESXi 5.0
-- when a customer's ESXi 5.0 server and FreeBSD 8.2 guest crashed.
Crash Details:
The keyboard/mouse usually stops responding for input on the
console; normally we can't type in a username or password. However,
we can switch VTs.
If there's a shell on the console and we can type, we can only run
things in memory. Any time we try to access the disk it will hang
indefinitely.
The server still has network access. We can ping it without issue.
SSH of course kicks you out because it can't do any I/O.
If we were to serve a lightweight http server off a memory backed
filesystem I'm confident it would run just fine as long as it
wasn't logging or anything.
On ESXi you see that there is a CPU spike of 100% that goes on
indefinitely. No idea what the FreeBSD OS itself thinks it is doing
because we can't run top during the crash.
This crash can affect a server and happen multiple times a week. It
can also not show up for 180 days or more. But it does happen. The
server can be 100% idle and crash. We have servers that do more I/O
than the ones that crash could ever attempt to do and these don't
crash at all. Completely inexplicable.
Things we've looked into:
Nothing about the installed software matters. We've tried cross
referencing the crashed servers by the programs they run but the
base OS is the only common denominator due to the wide variety of
servers it has affected.
Storage doesn't matter. We've tried different iSCSI SANs, we've
tried different switches, we've tried local datastores on the ESXi
servers themselves.
HP servers, Dell servers -- doesn't seem to matter either. (All
with latest firmwares, BIOSes, etc)
VMWare gave us a ton of debugging tasks, and we've given them
gigabytes of debugging info and data; they can't find anything.
VMWare tools -- with, without, using open-vm-tools makes no
difference. I think we've done a fair job ruling out VMWare.
I think we've finally found enough data that this is definitely
something in the FreeBSD world. I'm going to begin prepping some of
the known crashy servers with more debugging. Any suggestions on
what I should build the kernel with? They never do a proper panic,
but I definitely want to at least *try* to get into the debugger
the next time it crashes. And when it crashes, what the heck should
I be running? I've never played with the KDB before...
Thank you for any suggestions and help you can give me
This sounds just like a race condition that happens under Windows 7
on this laptop. The race condition, as far as I can tell involves
heavy disk access and heavy network access, and usually leaves the
drive light on, while all activity monitors (alldisk, allcpu,
allnetwork) are still active, although on this laptop disk takes
priority, and network slows to a crawl. occasionally, the mouse will
stop working, along with everything else, but usually not. keyboard
is lower priority, and doesn't do anything.
You might want to check with mickeysoft, this might just be their
problem. This sounds so freaking similar to the issue I get, and I
think it's a race condition (shared interrupts??).
This laptop is a Compaq Presario C300 series, with the 945GM chipset
and a T7600 Core2 Duo CPU, with 3G of RAM.
{TOP POSTING CORRECTED}
I just started reading this tread, but I am wondering if I missed
something here. What does this have to do with Windows 7?

If any BSD devs are interested in access to our environment I think we could comply. I might even be able to get authorization to give you an account on the most crash-prone server which doesn't have any sensitive customer data on it. I think at this point we'd even be willing to pay someone to look at a server in this state just so we (and hopefully others) can benefit and hopefully we end up with a more reliable FreeBSD-on-VMWare for everyone. I know Doug mentioned running newer OS versions and that is definitely tempting but because it's not 100% reproducible on demand it's hard to prove it fixes it without waiting 6 months. We're fighting internally here with trust 9.0 fixes it vs jump back to 7.4 because we KNOW it doesn't happen there. Having someone look at this and say oh, yes, that's a deficiency in mpt that appears to be fixed in the newer driver that was MFC'd to 8-STABLE and you'll find in 8.3-RELEASE and 9.0-RELEASE would be more comforting.

If it still crashes, we'll see what happens after that with those loader.conf options enabled. Um, if I may, that's something completely different. VMDirectPath, or PCIe passthru, is making a hardware device on a VMware host available directly to a guest. It'll take your LSI controller, in the example cited, and make it unavailable to VMware ESXi, and present it instead inside the guest environment. You do this when you have an app whose performance would suffer greatly when made to operate through the indirection that a VM naturally lives in; for example, it is quite common for FreeNAS users to pass a disk controller through to a VM guest in order to allow a virtualized FreeNAS instance to directly manage the physical disks. In that case, there are some issues with ESXi and interrupt delivery to the guest VM; virtualization doesn't actually get rid of the possibility of ESXi problems, since the hypervisor is still ultimately involved. It is certainly possible that there's some common issue involving interrupt delivery somehow, but I wouldn't get my hopes up.

Now the thing is that making a VM snapshot and deploying the snapshot a while later, or on a different (way less loaded) VMWare platform would basically make it perfectly usable again. Shutting down the VM and starting it again with only one CPU would also basically solve the problem. In a way Debian seemed to be able to survive the crisis but Disk I/O have latencies of many seconds, sometimes minutes. This would happen only on heavily loaded VMWare.

Re: Please help me diagnose this crazy VMWare/FreeBSD 8.x crash
Again, it's starting to sound like an interrupt handling issue which may or may not be limited to the storage device. You'll have to engage someone who knows those device drivers and likely have them add some debugging to the driver which can be easily flipped on (via binaries in a ramdisk - very important if you can't run sysctl because your disk IO has locked up!) to see what the current state of things. It's likely that the BSD mpt(4) and other storage drivers, and/or our interrupt handling code, is just slightly different enough to confuse the snot out of VMWare. I'd first look at the obvious - (eg, if you've just stopped receiving interrupts, even if new IO is scheduled). I'd also ask VMware if they have any tools that they can run on a VM to get the state of the internal emulated driver. For example, register dumps of the device to see if it's in a hung state, register dumps of the PIC/APIC to see what state they're in, etc. Maybe pull in someone like ixsystems and see if they can help debug this kind of stuff? If you're paying vmware for support, you could pull them into things with ixsystems and see if the two of them can help you sort this out?

Re: Please help me diagnose this crazy VMWare/FreeBSD 8.x crash
Hi, * have you filed a PR? * is the crash easily reproducable? * are you able to boot some ramdisk-only FreeBSD-8.2 images (eg create a ramdisk image using nanobsd?) and do some stress testing inside that? It sounds like you've established it's a storage issue, or at least interrupt handling for storage issue. So I'd definitely try the ramdisk-only boot and thrash it using lighttpd/httperf or something. If that survives fine, I'd look at trying to establish whether there's something wrong in the disk driver(s) freebsd is using.

vmware-tools-freebsd No drivers for x.org version: 7.6.5.
Hello, I have FreeBSD 9-CURRENT up and running in a VMware Workstation 7.x and I tried to install the vmware-tools-freebsd of VMware to get the driver for Xorg, but it seems that X.org 7.6.5. is not supported. My other VM runs a 8-CURRENT with X.org 7.4_1 which works fine. Any idea how to solve this? Should I go back to X.org 7.4_1 in 9-CURRENT? Or should I fake the vmware-tools installer to see X.org as /.4 while it is 7.6.5?

Thanks for help *S* You should be able find the screen dimensions for that MacBook Pro somewhere on the net. If my memory is correct and it's like my 13 acrylic MacBook then it will be something either 1280x800 or, less likely, 1280x720. I'm really old so I use an config file in the standard location: /etc/X11/xorg.conf configuration file to control X. If I understand correctly this is not longer strictly necessary. You can generate a base config by running: # X -configure That will write a file: xorg.conf.new into the current directory. For monitor setting I've never found anything on VMware Fusion, or the MacBook line that gives those numbers. I've been using: Section Monitor Identifier Apple MacBook Pro A1286 Display VendorName Apple HorizSync 27.0-86.0 VertRefresh 50.0-72.0 Modeline 1440x900 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync Modeline 1280x800 83.46 1280 1344 1480 1680 800 801 804 828 EndSection I'm using the Vesa Driver rather than the native vmware one so I'm pretty sure that the MacBook is actually handling the display settings. Again, there are instructions on the net for hacking xorg.conf specifically for VMWare Fusion and or Parallels to get a crisp display on a FreeBSD VM on a Mac. - I haven't found a way to map a key to Scroll Lock.

The FreeBSD console has a special mode where you can scroll back and forth in console output after hitting Scroll Lock. I'm just not sure what key on the Apple Keyboard VMware maps to Scroll Lock. (2) have a screen resolution of at least 800x600. To start, the X log file: /var/log/Xorg.0.log file is a good source of information about what X is doing if you are trying to tune things. Getting a good screen resolution should just be a matter of setting the refresh rates to match your monitor. You may be able to put any values you like in there since your screen and video adapter are virtual. All of this gets configured in /etc/X11/xorg.conf. I believe it's considered gauche to hand configure this anymore but since many modern displays, the Apple laptops included, don't conform to the VESA standard modes it's helpful to be able to tune things by hand. The problem is compounded by the fact that again, in VMware you probably aren't talking to the real hardware. Any modern hardware should just tell the X server what it's Sync and Refresh rates are. One final tip: Check the amount of VideoRam that VMware assigned to the virtual machine. I noticed that it was a little skint at 2Mb or something and I bumped it up to something larger than 8Mbso I could have a 1920x1080x24bpp display.

Otherwise the netmask of 255.255.255.0 will lead dhcpd to think it

VMware fusion / USB 2.0 issues.
Good afternoon, I'm having a problem with a FreeBSD virtual machine on VMware fusion v3.1.2. Basically I get no USB 2.0 functionality. When I plug in a USB 2.0 mass storage device I get: uhub_reattach_port: port 1 reset failed, error=USB_ERR_TIMEOUT uhub_reattach_port: device problem (USB_ERR_TIMEOUT), disabling port 1 With some devices I can fix the problem by reconfiguring VMware Fusion for USB 1.0 / 1.1 only. With others the device appears unwilling to negotiate with a USB 1.1 root hub and this is unusable altogether. I'm running FreeBSD 8.2 PRERELEASE based on the 2011/01 snapshot. If anyone else has seen this can come up with a work around I'd appreciate any assistance they could provide.
