Re: [Vserver] gentoo guest template stage4?!?
A stage4 is a tarball of a complete working system.

[Vserver] Major Upgrade Question
Hi. I'm using vserver successfully on a production server for over 1.5 years now. I have upgraded without major problems in the past, but it seems that there has been a pretty big change in revision numbers since my last update. This is a Gentoo host vserver and I am running vserver-sources v2.0.2.1 and util-vserver v0.30.212-r1. The upgrade will move me to vserver-sources v2.2.0 and util-vserver v0.30.212-r2. Does anyone think there will be any things I should watch out for with this upgrade? Will I need to upgrade anything in the guest os's after or before I upgrade the host? Thank you Sincerely, John ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
Re: [Vserver] Network - How is it implemented?
I was just going to ask the same thing. I didn't realize this was possible at all in the guest. Right now, I maintain the iptables rules on the host for all guests. I have guest admins send me a request via email if they need a new rule added, and then I add it to the host. The main problem is that opening a port because 1 guest needs it, opens that port for all guests and the host.

[Vserver] qmail-queue-scanner on vserver
I'm running vserver on Gentoo (host and guest) and I'm following this guide (http://gentoo-wiki.com/QmailRocksOnGentoo) for installing the whole Qmail Rocks set of packages. Everything seems to be working great except I can't get qmail-queue-scanner to detect spamassassin running. The way the build process works for qmail-queue-scanner, is it tries to detect what is installed and running and then customizes the perl script to use the detected services. I think the script is trying to detect if it's running by using localhost, so it keeps saying that spamassassin isn't running, even though it clearly is running. I guess my question is; Has anyone else been able to get qmail-queue-scanner installed and working properly with spamassassin on a vserver? I installed this same thing on a non-vserver system about 2 years ago and I didn't have this problem. So far, to troubleshoot, I have added the 'Remap Source IP Address' kernel option and rebooted. I've tried 127.0.0.1 localhost and myguestip localhost in the /etc/hosts file. My last attempt was to follow the wiki suggestion of adding a lo adapter. I can now ping 127.0.0.1 in the guest, but no change in the scanner program. Of course, I've already done the usual thing of looking for all instances of localhost or 127.0.0.1 and replacing it with myguestip. -John ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

As long as baselayout-1.13 is not stable, there will be no standard stages that work with vserver... you still have to use vserver stages until it's stable... baselayout-vserver still exists, and should be used in production environments, it will be removed after 1.13 is stable... probably i'll create a bunch of new stages meanwhile, so that upgrade loads will decrease..

Is this possible? It definitely is possible. I just moved a debian-vserver-guest to a xen-guest. A xen-guest is more or less configured like a real physical machine (except for the kernel and bootloader). Under debian I would install grub, and run 'grub-install', configure a kernel and place that kernel in the grub-config. What I did, was just to edit /etc/inittab, change it accordingly (I didn't get a login shell), and that's about it. If you have disabled your root-password (as I did in my vserver-guests), you would have to re-enable it. Networking-scripts might need to be adjusted, too (my xen hosts gets it from kernel level ip autoconfiguration). > - John HTH wogri -- [EMAIL PROTECTED] http://www.wogri.com http://www.einradfilm.at ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

[Vserver] Move vserver to real host
I have a guest os running on vserver that is configured and running great. I would like to move/copy that guest os to a standalone workstation. I am using Gentoo. It seems that if I make a tarball of the guest and then copy it to the workstation, change the profile, emerge the proper baselayout, install grub, I would think it should be ok.

Re: [Vserver] resource management
I'm sorry, I don't have an answer for you, but I do have a question. What is your cpu utilization with that many guests? I know that vserver is extremely easy on resources; however, I think on the wiki it says that some tests show 1-2% resource utilization per guest os. with 20 guest running, that's 20-40% resource utilization just for running empty guests. Of course, your not running empty guests (and you said some of the guests are heavily used), so I would expect your server to have very high resource usage. It may also help someone diagnose your problem by showing the output of vmstat.

Maybe..
As I always disable css at the flower page I didn't take it into
consideration.
The 'funky' signs are basically taken from 'ls -F' ( '/' for directory,
'@' for symlinks, '*' for executables. The rest are supplemented ('#'
for hash files, ''/'-' for number of lines in the files).
I think these signs are quite intuitive.

That depends very much on how much you allow to your guest (Capabilities). As VMWare uses a kernel module it makes no sense to try to run VMWare within a VServer guest.

Re: [Vserver] Multiple NICs, Multiple Networks; Revisited 2
Hi Bob. After reading both this thread and the one on the Gentoo forums that you posted, I see several problems. First, I would use seperate subnets for each of your eth0, eth1, and eth2 interfaces, and of course, seperate hubs/switches. I tried for a week to get 2 nics working on the same subnet and never got past the routing problems. For isolation reasons, I wouldn't expect that you would even really want them on the same subnet anyway. Second, it sounds like you are trying to use the same ip for your guest as the ip that you have set for your real interface. The guest os should have a unique address on the same subnet that the real interface is on. For instance, if eth1 has an ip of 192.168.18.252, then your guest os can have an ip of 192.168.18.100. Assuming that 192.168.18.100 is not already in use elsewhere. This leads to the third problem. Every guest os must have a unique ip address. In reading your posts, it sounds like you are trying to use the same ip for multiple guests. You can't do that. :) John On 8/13/06, Michael S.

[Vserver] Problem with ssh following cacti stat tutorial on wiki
Hi. I was trying to follow this tutorial: http://linux-vserver.org/Cacti+configuration on the vserver wiki. I'm running into a problem on the 4th step which says to type the following on the cacti machine: ssh -i vs-stat [EMAIL PROTECTED] I am still prompted for a password when trying this. Here's what I get: emsshop .ssh # ssh -i vs-stat [EMAIL PROTECTED] [EMAIL PROTECTED]'s password: Permission denied, please try again. [EMAIL PROTECTED]'s password: Permission denied, please try again. [EMAIL PROTECTED]'s password: Permission denied (publickey,password,keyboard-interactive). I have another key that I use from this server to the host server and it works fine for me. Here's what shows up in /var/log/messages: Jan 26 17:23:52 emsvs1 sshd[8159]: Failed password for vs-stat from x.x.x.x port 55460 ssh2 I'm not sure what to do next. Any help appreciated.

Re: [Vserver] Logo design
Some very nice ideas. I think a combination of the Linux Vserver on pg1 in the middle (the one with the darker 'v' checkmark) and the logo on the bottom left of the last page (pg. 11) would look perfect.

Thank you for you both for your help. It was just that eth1 was on the same subnet. Disabling eth1 for now has fixed the problem. I'll look into bonding the 2 nics.John On 1/14/06, Michael S.

[Vserver] Guest OS Stops Responding After Hours Of Working
Hi all. I'm using vserver on a Gentoo machine. I originally tried to get some help on the gentoo-vserver irc channel; however, I think we must all have opposite schedules.Anyway, I am using Gentoo for my host machine and also Gentoo as the guest os. The guest os runs Apache2 and MySQL and it works well for a while (5, 6 hours). After a while I am unable to connect to the guest os. From the host os, I can reach the guest os (ping, browse web page using links, etc), but not from outside the host os. If I go into the guest os using vserver myguest enter, the only fqdn i can ping is the one for the host os the is in my hosts file. No other fqdn's work. If I ping a known working ip address, everything starts working again! I have no idea what this means or how to fix it. As a temporary solution, just to keep my guest os working, I put a cron job that pings 2 different servers every half hour. I think it's probably a routing problem, but I'm not sure what to do. My host has 2 gigabit nics, both on the same subnet.Here is my ifconfig -a and route from my host os: (route hangs a while and then finally prints the output below) ---ifconfig -aeth0 Link encap:Ethernet HWaddr 00:04:23:C3:C4:FE inet addr:205.215.68.74 Bcast:0.0.0.0 Mask: 255.255.255.0 inet6 addr: fe80::204:23ff:fec3:c4fe/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:929466 errors:0 dropped:0 overruns:0 frame:0 TX packets:981291 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:255987202 (244.1 Mb) TX bytes:1085603257 (1035.3 Mb) Base address:0xecc0 Memory:df9e-dfa0eth0:100 Link encap:Ethernet HWaddr 00:04:23:C3:C4:FE inet addr:205.215.68.100 Bcast:205.215.68.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Base address:0xecc0 Memory:df9e-dfa0eth1 Link encap:Ethernet HWaddr 00:04:23:C3:C4:FF inet addr:205.215.68.75 Bcast: 0.0.0.0 Mask:255.255.255.0 inet6 addr: fe80::204:23ff:fec3:c4ff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:82354 errors:0 dropped:0 overruns:0 frame:0 TX packets:54663 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8731671 (8.3 Mb) TX bytes:71564782 (68.2 Mb) Base address:0xec80 Memory:df9c-df9e lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:28411 errors:0 dropped:0 overruns:0 frame:0 TX packets:28411 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:57095159 (54.4 Mb) TX bytes:57095159 ( 54.4 Mb)sit0 Link encap:IPv6-in-IPv4 NOARP MTU:1480 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)routeKernel IP routing tableDestination Gateway Genmask Flags Metric Ref Use Iface 205.215.68.0 * 255.255.255.0 U 0 0 0 eth0205.215.68.0 * 255.255.255.0 U 0 0 0 eth1loopback * 255.0.0.0 U 0 0 0 lodefault 205.215.68.254 0.0.0.0 UG 0 0 0 eth0default 205.215.68.254 0.0.0.0 UG 0 0 0 eth1Here is the ifconfig -a and route from inside my guest os: --ifconfig -aeth0 Link encap:Ethernet HWaddr 00:04:23:C3:C4:FE UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:929890 errors:0 dropped:0 overruns:0 frame:0 TX packets:981291 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:256023685 (244.1 Mb) TX bytes:1085603257 (1035.3 Mb) Base address:0xecc0 Memory:df9e-dfa0 eth0:100 Link encap:Ethernet HWaddr 00:04:23:C3:C4:FE inet addr:205.215.68.100 Bcast:205.215.68.255 Mask: 255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:929890 errors:0 dropped:0 overruns:0 frame:0 TX packets:981291 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:256023685 (244.1 Mb) TX bytes:1085603257 (1035.3 Mb) Base address:0xecc0 Memory:df9e-dfa0routeKernel IP routing tableDestination Gateway Genmask Flags Metric Ref Use Iface 205.215.68.0 * 255.255.25
