Subject: [PATCH] appliance: Use -cpu max.
|
||||
|
||||
QEMU has a newish feature (from about 2017 / qemu 2.9) called -cpu max
|
||||
which is supposed to select the best CPU, ideal for libguestfs.
|
||||
|
||||
After this change, on x86-64:
|
||||
|
||||
KVM TCG
|
||||
|
||||
Direct -cpu max -cpu max
|
||||
(non-libvirt)
|
||||
|
||||
Libvirt <cpu mode="host-passthrough"> <cpu mode="host-model">
|
||||
<model fallback="allow"/> <model fallback="allow"/>
|
||||
</cpu> </cpu>
