This patch set introduces changes within libvirt to lauch Qemu guests with Microsoft Hypervisor(mshv).
Qemu exposes this capability as 'mshv' accelerator type. Below is an excerpt of domain XML with mshv accelerator.:
``` <domain type='hyperv'> <name>qemu_mshv_test</name>
<os> <type machine='q35'>hvm</type> </os> ...
```
'mshv' accelerator within Qemu translates to 'hyperv' domains in Libvirt.
Changs in v4: - Adopted `query-accelerators` API to get mshv capabilities. - Fixed virtytpe parsing in schemas.
Chages in v3: - Addressed review comments on v2. - fixed qemucapabilitiestest case - Added a case to qemuxmlconftest
Changes in v2: - Addressed review comments on v1. - Added a test to verify mshv capabilities.
Eugene Fedorenko (1): qemu: Append mshv to hwaccel list.
Praveen K Paladugu (8): qemu: Introduce mshv capabilities qemu: Query and use mshv capabilities qemu: use mshv accel for hyperv domains qemu: conditionally add /dev/mshv to acl conf: Fix virttype handling in schemas tests: Add domaincaps case for mshv tests: qemucapabilities: Introduce MSHV capability tests:qemuxmlconftest: Add case for hyperv domains
