Hi,
I am trying to get the steal time with 2 VMs (each with 1 Vcpu) pinned
to same core.
While finding documentation on this, I came across your patches and
posts related to the implementation of this feature, so I thought it
would be best to ask you.
I run the same application on these 2 VMs

Hi!
I have connected my kvm guest using a macvtap interface and configured a
macvlan interface in bridge mode on the host to allow host to guest
communication.
If using virtio_net in the guest, host to guest transfer works fine. But
in guest to host direction large tcp segments do not arrive at
Hi,
But I think we could solve this in a different way. I think we could
just move the virtio configuration space to BAR1 by using a transport
feature bit.
Why hard-code stuff?
I think it makes alot of sense to have a capability simliar to msi-x
which simply specifies bar and offset of

Not sure, why the steal time information is not getting propagated to

Change existing kernel error message to include return value from
