Subject: [PATCH v2 0/6] nSVM optional features
Date: Mon,  1 Nov 2021 16:03:18 +0200	[thread overview]
Message-ID: <20211101140324.197921-1-mlevitsk@redhat.com> (raw)

This is a resend of a few patches that implement few
SVM's optional features for nesting.

I was testing these patches during last few weeks with various nested configurations
and I was unable to find any issues.

I also implemented support for nested vGIF in the last patch.

Best regards,
	Maxim Levitsky
