vda,snapshot=external --diskspec hda,snapshot=no
but when i tried to revert from the snapshot which created from the
above command ,i got error below:

[libvirt-users] /dev/tty only on a new container
by Sebastien Douche
Hi folks :),
I migrated the host from the Debian Squeeze to Ubuntu 12.10. Old
containers work but I can't use the ssh command, /dev/tty is missing.
On a new container, /dev/tty is here. The libvirt configuration is the
same.
Any ideas?
Thanks.

[libvirt-users] How to use xl (in place of xm) with libvirt 1.0.2 and Xen 4.2.1 in Ubuntu 13.04?
by Gizmo Chicken
QUESTION: What, if anything, can I do so that I can use xl (in place of
xm) with libvirt 1.0.2 and Xen 4.2.1 in Ubuntu 13.04?
BACKGROUND: I am testing a fully updated (as of March 27) installation of
Ubuntu 13.04 that includes the following packages:
libvirt - version 1.0.2-0ubuntu9
xen-hypervisor-4.2-amd64 - version 4.2.1-0ubuntu1
Upon setting TOOLSTACK=xm in /etc/default/xen (as well as making a few
needed tweaks to /etc/xen/xend-config.sxp), libvirt and virt-manager worked
great. Yippee!
I guess that I should be happy that the xm toolstack still works with Xen
4.2.1 and quit while I'm ahead, but...
According to libvirt's documentation:
"libxl: Starting with Xen 4.2, the legacy XenD/xm toolstack is deprecated
in favor of libxl, also commonly called libxenlight. libvirt supports this
new Xen toolstack via the libxl driver. If XenD is enabled, the legacy xen
driver consisting of the above mentioned channels will be used. If XenD is
disabled, the libxl driver will be used."
See http://libvirt.org/drvxen.html.
In view of the above, I attempted to use xl in place xm by setting
TOOLSTACK=xl in /etc/default/xen. And after doing so (both with and
without, the above mentioned tweaks to /etc/xen/xend-config.sxp), I
recieved the following error when attempting to start virt-manager:
Unable to connect to libvirt.

Verify that:

[libvirt-users] libvirtd using 11GB
by Alex Leonhardt
Hi All,
Am new to this list, and have asked in #ovirt / ovirt-users list and they
pointed me to here ... I've seen libvirtd using ~11 GB of resident memory
after the host has been running for about 60+ days with about 40 VMs
running on it.
The versions I'm currently running are :
libvirt.x86_64 0.9.10-21.el6_3.7
libvirt-client.x86_64 0.9.10-21.el6_3.7
libvirt-lock-sanlock.x86_64
libvirt-python.x86_64 0.9.10-21.el6_3.7
I know I can just restart libvirtd and "all should be fine" (and hopefully
I'll regain the 11GB of memory) - however, is there an updated version that
maybe fixes a memory leak ??
Thanks in advance,
Alex

[libvirt-users] Java client error on Windows 7 64 bit for Libvirt on KVM
by george john
Hi,
I need some help in building a Java client on Windows 7 64 bit plaftorm to manage a KVM using the libvirt APIs. Using the instructions at http://libvirt.org/java.html, i was able to build libvirt.jar. My understanding is that libvirt.jar uses JNA to call libvirt's native windows library. I tried using the libvirt dlls in the experimental Windows installation package mentioned in http://libvirt.org/windows.html at http://libvirt.org/sources/win32_experimental/Libvirt-0.8.8-0.exe
but whenever I try to connect to my remote API, I get the below Java exception :
Exception in thread "main" java.lang.UnsatisfiedLinkError: %1 is not a valid Win32 application.
at com.sun.jna.Native.open(Native Method)
at com.sun.jna.Native.open(Native.java:1718)
at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:210)
at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:322)

at org.libvirt.jna.Libvirt.<clinit>(Unknown Source)
at org.libvirt.Library.<clinit>(Unknown Source)
at org.libvirt.Connect.<init>(Unknown Source)
at Main.main(Main.java:8)
But when I try the same client code on a Windows XP 32 bit machine (with 32 bit JVM), I don't see this problem and the connection succeeds. So it looks like the problem is that I am not using 64 bit windows libvirt dlls. Is my assumption correct? Is there a Windows installer with 64 bit Libvirt dlls ? Or are the 64 bit version of DLLs published somewhere?
I tried using Matthias Bolte's msys_setup script (I tried in 2 machines) and in both machines, I get the below error when I try to run compile_libxml2.sh as per instructions https://github.com/photron/msys_setup/blob/master/readme_libvirt.txt

[libvirt-users] Basic Network Connections
by Slater, Joseph
Hi,
If I have these fragments in a domain definition, the guest will start with "eth0"
assigned by dhcp to an address on my lan. Things seem to work according to the documentation
I can find.
<network>
<name>direct-macvtap</name>
<forward mode='bridge'>
<interface dev='eth0' />
</forward>
</network>
<devices>
<interface type='direct'>
<mac address='00:15:17:A6:BC:C9' />
<source dev='eth0' mode='bridge' />
<model type='virtio' />
</interface>
</devices>
I don't understand the <network> part here. It doesn't seem to be documented. I inherited these pieces
so I do not know why they are as they are.
If, instead, I have the following, the guest comes up with no network interface at all
(except lo). On the host, interfaces vnet0 and virbr0 exist and virbr0 is 192.168.122.1.
<devices>
<interface type='network'>
<source network='default'/>
</interface>
</devices>
Adding in
<model type='virtio' />
makes it start with "eth0", but no address has been assigned. I can manually do that and then
I can communicate with the host but it's kind of a pain to add the address and routing manually.
Oddly enough, though, ping from host to guest works normally, but ping guest to host seems to succeed once
then hang (with no timeout).
It is not at all obvious to me how virtio magically creates eth0.
Am I doing something wrong, here? And, if anyone could advise how to use openvswitch
I'd appreciate it. I've seen adding
<virtualport type='openvswitch/>
might be enough, presumably with an appropriate name for the source network.
