Remove Old Kernel in PVE3

[apmuthu]

After an apt-get update and apt-get dist-upgrade and subsequent rebooting, sometimes the kernel gets updated.

Check existing pve kernels:

dpkg --list | grep "pve-kernel-"

Sample output:

ii  pve-kernel-2.6.32-20-pve         2.6.32-100                    amd64        The Proxmox PVE Kernel Image
ii  pve-kernel-2.6.32-22-pve         2.6.32-107                    amd64        The Proxmox PVE Kernel Image

Check Current Working Kernel:

# uname -a
Linux dc06 2.6.32-22-pve #1 SMP Mon Jul 15 08:36:46 CEST 2013 x86_64 GNU/Linux

and remove old ones:

apt-get remove pve-kernel-2.6.32-20-pve
update-grub

Check the versions now with # pveversion -v:

I did it like you described above because server rebootet is still under

dpkg --list | grep "pve-kernel-"

the old kernel is displayed that's right?

Using username "root".

The rc means residual packages after removal of the kernels. List them with:

dpkg --list |grep "^rc"

and then remove them as you removed the kernels.
