Since we rely on in-kernel kvm-apic implementation it's fine to set apic version as xAPIC which allows kernel to run in bigsmp mode.

This patch adds support for writing to zero refcount clusters. Refcount blocks are cached in like L2 tables and flushed upon VIRTIO_BLK_T_FLUSH and when evicted from the LRU cache. With this patch applied, 'qemu-img check' no longer complains about referenced clusters with zero reference count after dd if=/dev/zero of=/mnt/tmp where '/mnt' is freshly generated QCOW2 image.

PCI BAR probing is done in four steps: 1. Read address (and flags). 2. Mask BAR. 3. Read BAR again - Now the expected result is the size of the BAR. 4. Mask BAR with address. So far, we have only took care of the first step. This means that the kernel was using address as the size, causing a PCI allocation blunder. This patch fixes the issue by passing a proper size after masking. Signed-off-by:

Use the newly introduced KVM_CAP_MAX_VCPUS to determine max VCPU count the kernel side supports. Using more VCPUs than the recommended limit will issue a warning, using more than the absolute maximum will limit it down to the absolute maximum. Note this patch contains a hack to define KVM_CAP_MAX_VCPUS and should be removed when the kernel patch is merged with mainline. Signed-off-by:
