When we get a performance counter interrupt we need to route it on to the
Linux handler after we got out of the guest context. We also need to tell
our handling code that this particular interrupt doesn't need treatment.
So let's add those two bits in, making perf work while having a KVM guest
run
In some occasions even though a VM has terminated,
some remote shell sessions will take a long time
before giving up on the host. This situation is
happening frequently on subtests such as autotest:
The VM shuts down, but the session will be alive
for a long time after the VM died.
So let's keep t

Hi folks,
Host - debian 5.0
Guests - ubuntu 9.04 and windows vista
LAN - workstation, ubuntu 9.10
How to connect guests on the workstation and starting X ?
I can ssh connect the guests on their IP address with X forward. But I can't
start X of Ubuntu 9.04 (guest) on the workstation. rdeskt
Here is the new patch of V4 against tip/master of April 13th
if anyone wants to try it.
ChangeLog V4:
1) Based on Ingo's comments, I added help information around kvm
such like command-list.txt and perf-kvm.txt.
2) Added guest process id at the tail of kernel dso long name,
Below is the kernel patch to enable perf to collect guest os statistics.
Joerg,
Would you like to add support on svm? I don't know the exact point to trigger
NMI to host with svm.
See below code with vmx:
+ kvm_before_handle_nmi(&vmx->vcpu);
asm("int $2");
+
Add copying the keyval of guest test into client result dir so that server
can get it in autotest case.

Since gfn is not changed in the for loop, we do not need to call
gfn_to_memslot_unaliased() under the loop, and it is safe to move
it out.

Hi guys.
As the kvm does not support auto connection of USB device, unless

without any command input. And I know there is also qmp(qemu monitor

The VM screendump thread recently introduced generates
a lot of output on debug logs. Such output is not needed
most of the time (we are interested to see if a screenshot
production attempt failed though) and distracts the user
from other more important info.
