Hello,
Starting with kvm-40, I am not able to install a Win XP SP2 guest any more.
I consistently get a BSOD somewhere in the 2nd stage install.
Sometimes it is IRQL_NOT_LESS_OR_EQUAL, otherwise STOP: 0x008E
or STOP: 0x000A
In most failure cases I also get a kernel message:
emulation fail

Do not meddle in the internals of kernels, for they are subtle and quick to
panic.

The following patch uses net-tools (ifconfig and netstat) if /sbin/ip is
not available while trying to configure a bridge with the kvm wrapper
and qemu-ifup.
It also adds an option to the kvm wrapper to define which bridge device to
use instead of the hardcoded eth0 value (which is still the defa

64bit 2003 has a similar issue but, it doesn’t happen very time.
Did you have problem to boot smp win2k?
smp win2k on 64bit host got a blue screen in today's testing.
I also found that booting 4 linux guests may cause host to hang.
I tried to repeat the test case of booting 4 linux guests many tim

All my tests were 32-bit XP... that's probably the difference.
