Bug Description
Binary package hint: kvm
Hi,
the loadvm/savevm commands in kvm work unreliable for me. Loadvm tends to cause problems in the client virtual machine, I see random segfaults (e.g. login, swapper). For example: "swapper[0]: default at 080cb760 eip c011ec62 esp c0102f7c error 7". Sometimes the virtual console does not accept terminal input anymore.
I tried this both on a i386 and a amd64 machine with both hardy (0.62) and intrepid (0.69) with similar results.

Maybe releated (not sure). loadvm sometimes refuses to load at all:
$ kvm test-image -monitor stdio
QEMU 0.9.1 monitor - type 'help' for more information
(qemu) info snapshots
Snapshot devices: ide0-hd0
Snapshot list (from ide0-hd0):

[work]
I have no found a pattern yet, which ones load and which ones fail.
