Chris,
On the Linaro wiki there is an ARMv8 status page https://wiki.linaro.org/LSK/ARMv8
...that seems a bit out of date. It reports that KVM support on the Linaro 3.14 kernel had a "target" of release 14.10 (last October).
I see ~70 "arm64:" + "kvm:" patches added or backported to the Linaro 3.14 kernel. Is KVM considered 'supported' in the latest lsk-3.14? If yes, are there any known limitations or anything missing?
We have a customer interested in 3.14 on ARMv8 and would like to understand what I can say about KVM support on the Linaro 3.14 kernel.
Thanks, Stuart

We've backported most of the functionality and fixes up until 4.0, I believe.

The biggest weakness is probably lack of testing for virtualization purposes. I'm not aware of anyone haveing done any serious testing on LSK with KVM.
Cc'ing Kevin for his comments on the testing and status aspect.
Thanks, -Christoffer

We're not doing any thorough testing, but at kernelci.org we are doing basic boot testing of KVM guest on a few platforms (x86, arm, arm64.) Boot results/logs are available at kernelci.org[1]
