Отчет

This issue does not affect the versions of qemu-kvm as shipped with Red Hat Enterprise Linux 6, 7 and 8, as Virgl was not enabled in these versions. Support for Virgl was enabled as technical preview in Red Hat Enterprise Linux Advanced Virtualization 8.2, and later disabled in Red Hat Enterprise Linux Advanced Virtualization 8.3.
