[libvirt-users] EPT Misconfiguration

[Andrei Perietanu]

I am using libvirt 1.2.20. I noticed that when running some VMs (CentOS )
with 2G ram, 2CPUs each for some reason they go from 'state=running' to
'state=paused'; and they can't be restarted. They are un-usable.

When this happens I get the following in dmesg output:

[   46.595265] EPT: Misconfiguration.
[   46.595271] EPT: GPA: 0xfee000b0
[   46.595275] ept_misconfig_inspect_spte: spte 0x7e4968107 level 4
[   46.595279] ept_misconfig_inspect_spte: spte 0x7e4961107 level 3
[   46.595281] ept_misconfig_inspect_spte: spte 0x7e4960107 level 2
[   46.595284] ept_misconfig_inspect_spte: spte 0x7e592ff77 level 1

I have seen discussions about this topic, but for older code versions.
The problem happens often and I could not find a fix for it.
Has anyone seen this?Is there a fix for it?

Thanks,
Andrei
