Package: qemu-kvm
Version: 0.12.4+dfsg-1
Severity: important
I know you're going to hate this bug report, but this behaviour is very
consistent. I frequently copy large files from my Squeeze workstation to
my Lenny server (NFS) using the Dolphin file manager. While Dolphin is
hardly an exemplar of stability the copy works - despite frequent
short-duration freezes. I haven't tried it with other file managers - I
have an aversion to trying to make the system lock up. :)
However, when I am running a KVM Windows XP virtual machine on my
Squeeze box, most of the time the machine locks up during the copy. It
doesn't respond to keyboard or mouse and the file copy never completes.
All I can do is hit the reset button.
One potential candidate issue is that I'm using Samba to share the same
folders as NFS. This has been working for over a decade while I used a
separate Windows XP box. The problem has only cropped up since I started
using qemu-kvm. I'm never accessing the same files at the same time
(there is one share that both the Linux and Windows sessions both
access, but not the same files at the same time). However, the lockups
have even occurred when the XP session doesn't have any shares mapped.
