Subject: [Qemu-devel] [PATCH 1/1] x86: add CPU flags supported inside libvirt
Date: Thu, 18 Jul 2019 16:45:37 +0300 [thread overview]
Message-ID: <20190718134537.22356-1-den@openvz.org> (raw)
There are the following flags available in libvirt inside cpu_map.xm
<feature name='cvt16'>
<cpuid function='0x80000001' ecx='0x00040000'/>
</feature>
<feature name='cmt'> <!-- cqm -->
<cpuid eax_in='0x07' ecx_in='0x00' ebx='0x00001000'/>
</feature>
We have faced the problem that QEMU does not start once these flags are
present in the domain.xml.
This patch just adds proper names into the map.
