enable aes for guest
Hi,
How do I enable aes for guest VM? Host CPU supports aes (cat /proc/cpuinfo
has aes in its flags and virsh capabilities also displays aes as a
feature). When I add
<features> <aes/> </features>
to the xml file, I am unable to create the VM. It complains with the below
error:
virsh create /tmp/tmp.xml
error: Failed to create domain from /tmp/tmp.xml

LibVirt CPU problem
Hi,
I?m testing to start a KVM-VM with different CPU settings and I get an 
weird error when I use the parameter: <cpu mode='host-model'> !!
I have a AMD Opteron 4280 CPU, but in the VM, proc/cpuinfo shows me, 
that I?m using Intel core2duo cpu model T7700 and in the flag-line of 
proc/cpu the system is listing the svm-flag of AMD?!?! If I use <cpu

configuring a lxc guest to run 32bits from a 64bits host under libvirt-lxc
Hi there
I have a couple of newbie questions concerning running a 32bits guest in a 64bits host using libvirt - lxc; I’m running libvirt-1.2.5 on fedora18 and fedora20
(a) is this supported at all, and 
(b) if so how do I configure this for a given guest ?
guessing from the mere existence of http://www.redhat.com/archives/libvir-list/2011-February/msg01040.html
I would think the answer to (a) is

How to config qga to support dompmsuspend
Hi,
I tried to run domsuspend command on my PowerPC board but failed.

How to trigger a script in a guest after resume? (aka guest system clock incorrect after host reboot with suspended guest)
Hi
Is there a way i can trigger a script within a libvirt guest immediately
after resume? E.g. i don't see any log message that indicates to a guest
that it had been paused and was just woken up.
The problem that i am trying to solve is that when i reboot the host
(pausing all guests), the guests' system clocks are a few minutes late
after resume. The guests RTC (current_clocksource

[PATCH] drm/nouveau: Drop superfluous DRM_SWITCH_POWER_DYNAMIC_OFF checks
nouveau's ->suspend and ->resume callbacks are currently skipped if the
device's status is either DRM_SWITCH_POWER_OFF (powered off by
vga_switcheroo manual power control) or DRM_SWITCH_POWER_DYNAMIC_OFF
(runtime suspended).
In the former case this makes sense since the device is powered off
behind the PM core's back:  It will try to execute the ->suspend and

Live Migration with different hardware
Hi all,
I''m brand new to Xen and this list. I''m planning on using Xen. Especialy I''m
interested in the Live Migration Feature. Somewhere I read that the hardware
must be identical. What does this mean?
Will migration work from a P4 to a Xeon (Core2 Mircoarchitecure) ? Will
migration work if they got different NIC? What are the limitations?
Maybe someone does already

duplicated notifications for suspend and resume
Hello,
I am using domain event notifications from libvirt-event API in my application and it seems to work fine, except for 'suspend' and 'resume' events where I keep receiving duplicated notifications.
Similarly, the example provided with libvirt (in examples/object-events/event-test) also produces twice as much notifications for 'suspend' and 'resume' than for

redirecting guest serial to file on the host
Greetings,
I have a vm to which I can access using virsh console vm1/
I'd like in addition to be able to dump the serial of the vm in to a file on the host.

答复: How could I do the guest mount operation from the host?
Hi,
       I have tried usb and it doesn’t work. I don’t know if the filesystem tag could work…
I find in the formatdomain docs about the filesystem:
