When creating a guest with 2 virtio-net interfaces, i am running
into a issue causing the 2nd i/f falling back to userpace virtio
even when vhost is enabled.
After some debugging, it turned out that KVM_IOEVENTFD ioctl()
call in qemu is failing with ENOSPC.
This is because of the NR_IOBUS_DEVS(6)

Hello all,
As some of you might know, I've worked on supporting big real mode
emulation on VMX back in GSoC 2008. Looking at the Qemu GSoC ideas
list for this year, I found it among the possible ideas for a GSoC
project. I'd be interested in driving this feature towards completion,
and I have a few

Hi there,
not really trying to get into the CC list of this discussion ;) but
for what is worth I'd like to share my opinion on the matter.

This patch changes the command line invokation of kvm_config.py from this:
./kvm_config.py --verbose -f
to this:
./kvm_config.py --verbose
and also makes the dict printing code slightly shorter.

- Add kvm_utils.get_sub_pool() which splits a MAC-IP pool in several pieces.
- Use get_sub_pool() in kvm_scheduler immediately before launching a test.

Hi,
since the default CPU model for QEMU (qemu64) is an AMD K7, the Linux
kernel complains and taints the kernel when it detects multiple
processors. The reason for this is a check for SMP safe CPUs in
arch/x86/kernel/cpu/amd.c:amd_k7_smp_check(). In recent kernels (since
about 2.6.29) this i

Yes. On Intel hosts only, and controlled by bypass_guest_pf.
