we have a kvm that would not boot after pve upgrade yesterday. this debian etch kvm that has been working on this host since at least 12/2012 .
at console:
Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with ap
and send a report. Then try booting the 'noapic' option
On another system with a different host hardware and same pve version , etch kvm does work.
host cpu differences [ I am not certain that the cause of issue is a cpu difference. ]
does not work: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
works on: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
/etc/pve/qemu-server/8101.conf
fbc89 ~ # pveversion -v
---------------------------
attempt solutions:
CPU type : host --> qume32 . nope.
# http://forum.proxmox.com/threads/1496-Kernel-panic-not-syncing-IO-APIC-timer-doesn-t-work! mentions e1000 . so try changing nic type
NIC : e1000 --> rtl8139 . OK
