vmport: unknown command 13

vmport: unknown command 13

[Elmar Haneke]

After movong from KVM-72 to KVM-73 I do get the Notice

"vmport: unknown command 13"

The Message appears on starting emulation. In an Netboot environment it
does appear before booting from Network is asked.

What might go wrong here?

It's actually harmless; it's the Bochs BIOS trying to access the vmport function
13, which means "give me your UUID".  However, upstream Qemu (and hence, KVM)
doesn't support this function, so that's where the error message comes from.  If
I understand it correctly, upstream Qemu now has suppressed this warning
message, so the next time KVM syncs up, the message will disappear.

it is a bug from qemu's vmware backdoor that has been fixed already upstream,
and that shouldn't be printed unless debugging that interface (not all
commands had been implemented already)

it is harmless and can be ignored for now or you can just pull the patch
from qemu upstream if you don't want to wait until the next merge :
