Hello,

I have an issue with vzmigrate in proxmox 1.8 doing an online migration:

Proxmox installation was with Bare-metal ISO Installer.

Thank you very much for your help.

if you need openvz online migration you need to use the stable openvz, 2.6.18 (see http://pve.proxmox.com/wiki/Proxmox_VE_Kernel#Kernel_2.6.18)

xelkano · May 24, 2011

Thanks for your fast reply!

Is possible to see somewhere current bugs on 2.6.32 kernel branch?

Best regards.

Yes, the two machines failes anytime i want migrate over the proxmox interface. Is there a advanced logging?

I need exact steps how to reproduce the bug here. I does not help if you can reproduce the bug at your location.

There is one open bug regarding init logger. Maybe it works when your set INITLOG=no in /etc/vz/vz.conf

valshare · Sep 14, 2011

Hi Dietmar,

thanx, that works. Why INITLOG=yes is default on? I have switched it off in a old configuration. A Update override my settings and switched the parameter to yes.

Regards and big thanx,

Valle
