Downgrade the kernel to pve-kernel-2.6.32-4-pve (How ?)

[xReaper]

Hello, can someone confirm that i can remove new kernel pve-kernel-2.6.32-6-pve with "aptitude remove pve-kernel-2.6.32-6-pve" and it will boot on the old one ?

pve-kernel-2.6.32-4-pve

proxmox-cbv1:~# pveversion -v
pve-manager: 1.9-24 (pve-manager/1.9/6542)

Can i set running kernel maybe somewhere ? My VM's are unstable on this kernel and i would like to downgrade.

Thank you very much.

I did it in two steps:

1. Install the appropriate kernel:
apt-get install pve-kernel-2.6.32-4-pve

2. Edit /boot/grub/menu.lst, so that the desired kernel version is first in the list.

I'm interested in receiving updates for the new kernel branch, so I would not remove it.

pveversion -v shows that the old is already there, so just edit the menu.lst as gkovacs suggests.
