On AMD some bits from 1.EDX are reported in 8001.EDX. The mask used
to copy bits from 1.EDX to 8001.EDX is incorrect resulting in
unsupported features passed into a guest.

It is not safe to retrieve the KVM internal state of a given cpu
while its potentially modifying it.
Queue the request to run on cpu context, similarly to qemu-kvm.

Remove this check in an effort to allow kvm guests to run without
root privileges. This capability check doesn't seem to add any
security since the device needs to have already been added via the
assign device ioctl and the io actually occurs through the pci
sysfs interface.

The PCI config space bin_attr read handler has a hardcoded CAP_SYS_ADMIN
check to verify privileges before allowing a user to read device

Hi,
Does anyone have any idea on a issue that I have regarding VM migration from
AMD to Intel host?
When the guest is migrated from AMD host and right after it starts on Intel
host,
qemu process crashes with log messages like below.
Looks like, when the guest is loaded on its network, it is

One alternative would be:

Hi, Benjamin, Paul, Alex,
Please see the patches 6,7/12. I first say sorry for that I've not tested these

will be happy if you would give me any comments.
Alex, could you help me? Though I have a

Does C do the + or the / first? Either way, I'd like to see brackets here :)
OK, I'll change like that! I
