Package: qemu-kvm
Version: 1.1.0+dfsg-3
Severity: normal
Dear Maintainer,
after upgrading the host system from squeeze to wheezy a guest
system with wheezy does not boot anymore.
Before the upgrade the same guest system was running without
problems with the following options (with squeeze as host system):
$ kvm -smp 2 -m 512 -drive file=/local/kvm/wheezy.img,index=0,media=disk
When I disable the smp option the guest system also boots with
wheezy as host system. It even boots successfully with very low
RAM settings:
$ kvm -m 48 -curses -drive file=/local/kvm/wheezy.img,index=0,media=disk
# free
total used free shared buffers cached
Mem: 43388 38856 4532 0 2588 20328
-/+ buffers/cache: 15940 27448
Swap: 489944 132 489812
When I enable the smp option with wheezy as host system I have to
give the same wheezy guest system at least 927 MB of RAM to be
able to boot:
$ kvm -smp 2 -m 927 -curses -drive file=/local/kvm/wheezy.img,index=0,media=disk
# free
total used free shared buffers cached
Mem: 935632 47060 888572 0 2932 24264
-/+ buffers/cache: 19864 915768
Swap: 489944 0 489944
If I supply less than 927 MB of RAM the guest boot fails with the
following error messages:
$ kvm -smp 2 -m 926 -curses -drive file=/local/kvm/wheezy.img,index=0,media=disk
