[PVE-User] Is it safe to upgrade from Proxmox-ve-2.6.18 to Proxmox-ve-2.6.35 at one shot?

[Martin Maurer]

I recommend everybody to go for the 2.6.32 branch, best maintained and updated regularly.
One of the upcoming versions will stable OpenVZ (and also KSM).

Yes, 2.6.35 kernel supports only KVM, not OpenVZ, see :
http://pve.proxmox.com/wiki/Proxmox_VE_Kernel

I am using 2.6.35 kernel, as I am only using KVM, and windows 2008 (standard and R2) VMs install just fine.

Thank you for the input guys.

Jeremy, are you saying that 2.6.35 doesn't support OpenVZ containers? I can only have KVMs?    ???

I do have a problem. I am tried installing Win 2008 server on 2.6.18 and it gets stuck at "Loading files...."
I know this is fixed in newer versions.

Hi Bruce,

AFAIK 2.6.35 doesn't include OVZ, only KVM so unless you have no OVZ VMs I wouldn't go to the latest kernel. All 3 kernel branches are updated so just because you are using 2.6.18 doesn't necessarily mean your PVE is out of date, just that you are not using the latest kernel (ie you can update to the latest version of the 2.6.18 kernel). Personally i am using the 2.6.32 kernel branch and it works well with OVZ and KVM but YMMV - if 2.6.18n is working fine for you no need to upgrade it (ie just omit the last line of code in your example).

Have a read about kernel branches on the PVE wiki for full details (and to confirm my suspicions).

Good luck!

Regards,
Jeremy

Did you update your grub (sudo update-grub) after upgrading package
and notice that you have by default choosing kernel 2.6.35 on boot?
