Re: [libvirt] [RFC PATCH v2 REBASE 00/18] Introduce vGPU mdev framework to libvirt

On behalf of Yongli, He who tested these series with KVMGT vGPU mdev. Hi, Erik Here is the libvirt testing result. in general speaking, it works well. while start libvirt-d and starting the vm, there are some call traces, i attached them in the very end of this mail. this mail will be the test-by content later.
