Subject: [PATCH v2 0/2] KVM: nSVM: few fixes for the nested migration
Date: Tue,  4 May 2021 17:39:34 +0300	[thread overview]
Message-ID: <20210504143936.1644378-1-mlevitsk@redhat.com> (raw)

Those are few fixes for issues I uncovered by doing variants of a\r
synthetic migration test I just created:\r
\r
I modified the qemu, such that on each vm pause/resume cycle,\r
just prior to resuming a vCPU, qemu reads its KVM state,\r
then (optionaly) resets this state by uploading a\r
dummy reset state to KVM, and then it uploads back to KVM,\r
the state that this vCPU had before.\r
\r
V2: those are only last 2 patches from V1,\r
updated with review feedback from Paolo (Thanks!).\r
\r
Best regards,\r
	Maxim Levitsky\r
