Problems after Proxmox update to v1.5

After the update of Proxmox to version 1.5 and a reboot of the host all virtual qemu server (using KVM) where not booting up. It does not matter if it is a Windows XP or Windows 7, they stop there:

Starting SeaBIOS ( Version ......)

gPXE (htt://....) - 00:03.0 C900 PCI2.10 Pnp BBS PMM7FE0@10 C900

Press F12 for boot menu

So also trying to boot from CD-ROM will not help in that case. After some search on the web i found the solution in the Proxmox forum.

So the System was missing some packages, you can easily solve this with:

aptitude update && aptitude upgrade && aptitude install proxmox-ve-2.6.24

After reboot if you enter

# pveversion -v

you should find there the actual packages which correspond together. At the time of writing:
# pveversion -v
