Re: [Users] Big comparison Ploop and ext4 vs simfs vs ZFS
The point is that in your use case ZFS works very well and saves you 1TB of disk space. Great for you. For my use case the overhead of learning and deploying ZFS greatly outweighs the handful of GBs I might potentially save in disk space. Don't get me wrong, but zfs is totally simply to use and deploy - much simpler than anything else (considering all the great feature it provides). ___ Users mailing list Users@openvz.org https://lists.openvz.org/mailman/listinfo/users

Re: [Users] OpenVZ and ZFS excellent experience
Unless I misunderstood, they also say there that ZFS code can be merged into the Linux source tree... but that distributing a binary built from it would be a no-no. They claim distributing as binary module is no problem! They have split the code into spl (Solaris porting Layer), and a separate zfs module which use the SPL interface. That make it really hard to claim that zfs is derived work from Linux. They can say a lot of things but what really matters is how the distros behave. So far almost no distros include ZFS kernel modules and related support packages... and (I believe) the reason is that they want to mitigate risk. Quite a few ship the fuse-based ZFS stuff. I believe the small handful of distros that do include ZFS support via kernel modules are located outside of the US. see: http://warpmech.com/?news=myth-busting-series-zfs-on-linux-has-license-problems That article claims that Lawrence Livermore National Lab already ships binary zfs modules to customers. With regards to OpenVZ it mostly matters what Red Hat does and clones. I know Proxmox is a huge Debian fan... does Debian offer ZFS kernel modules and if not, why not? How about Proxmox VE? Proxmox is working on that. You can link to libzfs. As example, see grub code. Grub is GPL and they link with libzfs. Do I miss something? Again, are distros shipping grub2 with or without ZFS support? Proxmox VE will ship grub with zfs support. But I think further distros will follow soon. ___ Users mailing list Users@openvz.org https://lists.openvz.org/mailman/listinfo/users
Re: [Users] OpenVZ and ZFS excellent experience
I know Proxmox is a huge Debian fan... does Debian offer ZFS kernel modules and if not, why not? How about Proxmox VE? Besides, I would like to improve support for more storage types on OpenVZ. I think direct support for zfs, rbd, dm-thin would be great (snaphshot, clone). But for me the current OpenVZ status is a bit unclear, because of the announced move to virtuozzo-core. I guess that means the OpenVZ vzctl code will be completely replaced? And when can we expect a first release? ___ Users mailing list Users@openvz.org https://lists.openvz.org/mailman/listinfo/users

[Users] inaccurate timers with ovzkernel-2.6.18-164.11.1.el5.028stab068.3
We run kvm on ovz kernels. But it seems that the latest ovzkernel
has problems with posix timers, so kvm mouse movement in not smooth.
By default kvm uses timer_create() and timer_settime() syscalls.
To show the behavior I use the following command:
/usr/libexec/qemu-kvm -drive
file=ubuntu-9.04-desktop-amd64.iso,if=ide,index=2,media=cdrom -m 512 -net none
-clock dynticks
Everything runs normal when I use any other timer option ('rtc' or 'unix'). For
example
this works perfectly:
/usr/libexec/qemu-kvm -drive
file=ubuntu-9.04-desktop-amd64.iso,if=ide,index=2,media=cdrom -m 512 -net none
-clock unix
I also tested with standard redhat kernel without openvz patches - everything
work well there.
We run on debian, but you can also reproduce the bug on RHEL/CENTOS with the
packages provided by opennode:
# wget
http://opennode.activesys.org/CentOS/5/opennode/x86_64/RPMS/ovzkernel-2.6.18-164.11.1.el5.028stab068.3.x86_64.rpm

As the type of fanboy I am, that does not frustrate me at all but I realise how frustrating that can be to others. I would indeed call that a limitation.

This is caused by the need for features like CONFIG_INOTIFY_USER, CONFIG_SIGNALFD and sysfs improvements so it cannot be resolved with trivial patches (I already did this to not require 2.6.27). The last version which supports 2.6.18 is 145 and it cannot be used with squeeze anyway without a substantial effort because other packages depend on newer versions.

RE: [Users] Remote storage and migration
Hello, list. I've been using OpenVZ since last year. Now I'd like to configure the cluster I've been using to use remote storage, so that migrations do not require to copy the container's filesystem. Reading the wiki and the forum, I've learned that NFS is not recommended, but I don't know why. iSCSI has been suggested as a way to go, although no success story supported the suggestion. Finally, somebody said that he was using GFS without problems, but one of the OpenVZ developers said (at that time) that GFS was not recommended due to stability issuess. I've been told that remote storage with OpenVZ is not a well-known area, but I have to ask anyway, so as to leverage in previous experiences. Any information is welcome, even more the problems that were found with each approach, so that I know were to go and were not to. I am also interested to make openvz more flexible. The new proxmox release will have a very flexible storage model which supports iscsi/nfs/lvm, but it is currently KVM only, because openvz lacks that feature. I am especially interested in mounting devices (lvm) as container root, something like # mount -t ext3 /dev/xzy /var/lib/vz/private/777 Looking at the source (vzctl/src/fs_simfs.c vz_mount) it seem to be easy to implement. If ROOT is a device we use 'ext3' instead of 'simfs'. But I have no idea how this interacts with the rest of the openvz code? Does quotas work that way? Or would it be better to use an additional configuration option to specify the root device: ROOTDEV=/dev/xzy ROOT=... PRIVATE=... We then simply mount ROOTDEV first, then use simfs as usual? I can write that code if some of the OpenVZ developers give me some hints. - Dietmar ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

RE: [Users] Suggestion for a new parameter: PRIMARY_IP
I read that manpage multiple times, trying to figure out what exactly happens when. It states that specifying INADDR_ANY is equivalent to not calling bind() at all before connect(). However if you read closely, it does not state the semantics of such situation for active sockets (i.e. sockets you call connect() on, as opposed to sockets on which you call listen()/accept()). In fact I could not find any documentation on such behaviour on the internet, so I read the Linux source code. The description in the footnote of my initial email in this thread is my interpretation of what happens (which matches experiments I made). Ok, I was not aware of that. What application are we talking about? Oh, just about anything that does: socket(); connect(); (without a bind() in between), for example default usage of wget, telnet, ssh.. any TCP client really. If you have a server using several IP addresses, the client IP address used by tcp client is undefined. But what application depends on the client IP used?

So how can I create a VM with a password? For example: # vzctl create # vzctl start # vzctl set --password can also fail because the network is not running when we execute the passwd command (vzctl start does not wait until the network is fully functional, and passwd requires the network when it uses nis).

AW: [Users] ovzkernel-xen ?
Having not used Xen but being very interested in all forms of virtualization and how folks are using it, I'm curious. What does one do with a kernel that does both OpenVZ and Xen? Do you run multiple Doms and a few of them use OpenVZ? Is there a reason that neither OpenVZ nor Xen do exactly what you want by themselves? Yes, there is a fundamental difference in how the two systems work, RTFM :) For example with Xen each child gets a whole new kernel instance with everything that that entails, most obvious example being separate memory. On Proxmox VE (pve.proxmox.com), we combine KVM and openvz. That way we are able to run fully virtualized guests (i.e. windows) and openvz CTs. - Dietmar ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

[Users] Multiple bridges and firewalls
Hi all, with the new vzctl bridge patch sent yesterday it is easy to build up hosts with complex 'virtual' networks. In Proxmox VE we have 9 bridges - each CT can connect to one or more bridges. I guess in theory it is possible to run a fully functional firewall inside a CT. Does somebody has experiences with that? Also, when you assign ip addresses to the bridges, the host routes between those bridges. If you want to restrict traffic you need to setup a firewall on the host. I just tried shorewall, and it seems to work perfectly. Does somebody else using shorewall with openvz host? - does it work reliable? Are there other 'simple' solutions besides shorewall? - Dietmar ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

Betreff: Re: AW: [Users] Multiple bridge support
How do you invoke it? Using EXTERNAL_SCRIPT?
Would be good to have a patch adding (conditional?)
invocation of vznetaddbr to vznetcfg.
One idea was to add a new global option in vz.conf:
DEF_BRIDGE=
If set, we automatically setup the bridge (we need to pass an additional
parameter to vznetcfg, but i guess thats no problem at all). That also
avoid a hardcoded default bridge name (vmbr0).
Here is the totally untested code. If you like the idea I will test it

AW: AW: [Users] Veth mac generation
Do I understand correctly that you actually experience the following problem: 1. veth MAC address is lower then your ethX MAC. 2. so brX is assigned min(vethX-MAC, ethX-MAC) which is vethX-MAC. 3. and what is the your problem with that? that host system MAC changes dynamically and networking breaks or what? The host gets unreachable for about 20 seconds (because ARP mappings are wrong now) I just can't see how fully random 6 bytes MAC can help. Because sometimes it will be low enough as well and you will hit the problem anyway. Well one idea was to assign macs starting with 'fe' - but ist not a good idea anyways. If I got your problem right then I can advise you a possible solution - in RHEL5 kernel we have a functionality called via_phys_dev (triggered by BRCTL_SET_VIA_ORIG_DEV ioctl). This forces kernel to work with original interface ethX (first added to bridge) and pass the traffic to it. This allows to add ethX to bridge w/o need to propogate it's netfilter rules and other settings to brX. Interesting - thanks for that hint. - Dietmar ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
