qemu-kvm-0.12.3 is now available. This release is based on the
upstream qemu 0.12.3, plus kvm-specific enhancements. Please see the
original qemu 0.12.3 release announcement for details.

Looks good to me. It will definitely boost test speed for certain
tests and give flexibility to use existing autotest strength in more
granular way.

Good to see this test. Overall structure looks fine except comments below.

MCE registers are saved/load into/from CPUState in
kvm_arch_save/load_regs. Because all MCE registers except for
MCG_STATUS should be preserved, MCE registers are saved before
kvm_arch_load_regs in kvm_arch_cpu_reset. To simulate the MCG_STATUS
clearing upon reset, env->mcg_status is set to 0 after

Hi,
I read some kernel source. My basic understanding is that, in
net/8021q/vlan_dev.c, vlan_dev_init, the dev->features of vconfig
created interface is defined to be
dev->features |= real_dev->features & real_dev->vlan_features;
However, in drivers/net/virtio_net.c, vlan_features are never set (

- Makes kvm_config use less memory during parsing, by storing config data
compactly in arrays during parsing, and generating the final dicts only when
requested.
On my machine this results in 5-10 times less memory being used (depending on
the size of the final generated list).
I'm running qemu-kvm-0.12.2, compiled from source on Debian lenny
(stable), amd64 architecture (Xeon).
The VM is running Debian squeeze (testing).
When it starts up, the boot screen appears to be 640x480. If I launch

Drop kvm_load_tsc in favor of level-dependent writeback in
kvm_arch_load_regs. KVM's PV clock MSRs fall in the same category and
should therefore only be written back on full sync.

Hi,

for virtualization. Rather than continuing to have discussions in
smaller groups, I think it is a good idea we move it to the mailing
lists to see what we can share and avoid duplicate efforts.
