hi ，everyone! I am a newcomer to Libvirt, and I don't know if it's a native question, I create snapshots of virtual machines that use encrypted disk, The console gave me the following error: Traceback(most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py",line 4613, in snapshot self._dom,snapshotCreateXML(snapxml, snapFlags) File

Hi Libvirt, Does libvirt-python currently support the creation of external snapshots? I ran domain.snapshotCreateXML(xml) where xml is <domainsnapshot> <name>snap1</name> <description>Snapshot of OS install and updates</description> <disks> <disk name='vda'> <source

Hi there, I've been happily installing VMs in CentOS 5.2's Xen implementation using virt-manager. However, my latest attempt to use the install wizard in virt-manager failed when I got to the networking screen. The 'forward' button was unresponsive, and I was unable to proceed. I checked the virt-manager logs, and saw this appearing immediately after I tried to proceed:

Hi, dear friend. My guest has two disks, vda and vdb. both are qcow2 local file. When guest running state. I want to take the vda snapshot of guest(just vda, no include vdb). but I met libvirt do snapshot for all disks of guest. About methods for follow: 1、 ``` bash virsh snapshot-create-as 8x0lbzvS --name sys_disk3 --disk-only --diskspec "vda,snapshot=external" ``` ``` result

I keep getting an error when I try to attach a device in the libvirt api through python The python code is: conn=libvirt.open('qemu:///system') dom = conn.lookupByName("fedoratest") if dom.info()[0]==1: dom.attachDevice('net.xml') And I keep getting: "libvirtError: XML description not well formed or invalid The xml is a simple network

Hi, I''m running snv84 on a SunFire x2200M2, 2 dualcore opterons, 8GB ram, 2 mirror sata disks (zfs). I tried to install both Ubuntu 7.1 Desktop and Fedora 8 into a HVM domU but failed everytime. The VNC-Server for the domU dies, but the domain still consumes CPU time, disks go idle after a while (zpool iostat or iostat show zero I/O). The domUs booted up fine, the installer started,

Hello everyone, I am trying to find a way to store an internal disk snapshot and supposed to restore later. Here is the problems I met: 1) when I use SnapshotCreateXML() to create a disk_only snapshot while the domain is inactive, there is an error happened: disk snapshot of inactive domains not implemented yet. I am wondering is there and way I can save the disk_only

I'm writing an app and using the Python bindings for libvirt. Everything is fine but, in some cases I need to call lookupByName(). There are a lot of times when the name will not exist, I trap the exception, however I still get this message printed to stderr: libvir: QEMU error : Domain not found: no domain with matching name 'foo' Is there any way to turn this off? This is a

Hi, I am trying to check if a domain exists by using the libvirt python API *"lookupbyname()*". If the domain does not exist, it prints an error message on the console saying "*Domain not found*". I need the errors or logs only in syslog. I have tried redirecting stderr and stdout. But, it doesn't have any effect. I have also tried playing around with the libvirt logging

Hi. Since the update to libvirt-1.3.2, virsh keeps disconnecting from qemu:///session. Weirdly enough, qemu:///session works fine for root, and qemu:///system works for both the user and the root. With the same configuration(tarball with files from /etc/libvirt attached), libvirt-1.3.1 works without problems. From the virsh debug log(attached): --- grep error virsh.log.1.3.2 2016-03-03

Hi, I have another question, when I do the blockcommit command and get the result " Top image as the active layer is currently unsupported ", is it being developed? root@cvk-31:/vms/images# virsh blockcommit Vmtest /vms/images/Vmtest1;echo $? error: internal error unable to execute QEMU command 'block-commit': Top image as the active layer is currently unsupported 1 But as I

Greetings, I am developing a platform for test and debug use. The typical scenario I want to realize is the following: I run a .qcow2 image via QEMU-KVM, the running OS is not relevant. I want to take several snapshots of both Disk and RAM status; same file, separate files doesn't matter. I just need a way to have consistent information about them (better with XML description) and the data
