[Vserver] which version to choose for a new install
Hello, If we want to build new box with vserver on them, what version stable/dev/prepatch should we choose ? We know the kernel has seen some major bug squeeze those last weeks and stable version is laggin a little in kernel version. So what is the best choice about this ? should we stick with stable and be .0.01 late in kernel or take dev one, will this be a problem ? will version be switched soon (dev=stable) as hints on the list seems to indicate ? Any advice on wich version to choose ? :) -- Cordialement, Ghislain smime.p7s Description: S/MIME Cryptographic Signature ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
[Vserver] vserver bug on kernel 2.6.18.3
Hello, I compiled kernel 2.6.18.3 with patch-2.6.18.3-vs2.1.1.1.diff on debian-3.1-sarge-backports Compil ok, starting ok but when i launch vserver vweb1 start, i got the following errors which seems to be the same as Andreas Baetz. I've read Herbert should fix it in the next release . It was just to show the bug is probably in the patch-2.6.18.3-vs2.1.1.1.diff , too.

[Vserver] future vserver on ubuntu
It looks like Ubuntu is no longer going to include kernel-patch-vserver in the distribution. It's not in feisty. The patch included in edgy does not apply to the stock linux sources (2.6.17) and edgy does not include 2.6.12/2.6.13/2.6.15 which the patch requires. And, there are no images at ubuntu.uni-klu.ac.at. Does anyone know what the plans are?

(i'm interested in how ubuntu handles supporting people/companies/organizations running dapper long-term but needing to support newer machines not supported in dapper's 2.6.15. is dapper's long term support for hardware going to be stuck in the year 2006?) hth. corey -- [EMAIL PROTECTED] ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

I tried vs2.0.2.2-rc8 with 2.6.18.3, the vserver starts ok, no errors, but when I stopped it, the whole system freezed. Right after Deconfiguring network interfaces...done. Nothing worked besides magic sysreq-boot. Nothing in the syslog. Didn't try a second time due to lack of time.
