Hi , I am trying to perform offline migration (i.e) Create an incremental image using the qcow format, transfer the vm memory state to a state fie.Use the image and statefile together as a template. Now create a new vm using the template. I can successfully do it using the following commands : Save phase : stop migrate "exec:gzip -c > STATEFILE.gz" qemu-img qemu-img create -b

I've got a problem where I can't access my console (well, I can', but I can't type in a password), which I don't think is a libvirt issue but any help or commentary is certainly welcome http://thread.gmane.org/gmane.comp.emulators.kvm.devel/79561 , and I'm trying to debug it by trying out different console/serial options in my .xml file, and I can't change them. What I

hi all, (this events ocurred before my previous mail about the uuid incident) so, I installed a vm host: rhel6 guest: centos6 network: bridge (br0, eth1 as slave) but then, I changed the name of the bridge from br0 to br1 (because br1<->eth1 seems pretty than br0<->eth1) so: - mv /etc/sysconfig/network-scripts/ifcfg-br0 /etc/sysconfig/network-scripts/ifcfg-br1 - edited

Hi, These are my doubts: 1. I tried live migration of Ubuntu 11.04 from the one physical machine to another using the migrate() function. I connected via tcp in the destination URI and migrated successfully(lesser than 2 seconds). I tried running virsh list --all on the destination PM and confirmed that the VM had been migrated successfully. When I tried checking ps aux | grep vmname where

Dear, I encountered some problems when I used the virsh to start my virtual machines. I had tried some ways but I still couldn't solve it. Please help me, thanks. error messages : virsh # start controlnode error: Failed to start domain controlnode error: internal error process exited while connecting to monitor: bind(unix:/var/lib/libvirt/qemu/controlnode.monitor): Permission denied

Hi all, Where could I find the memory dump and disk snapshots for vm after command "virsh snapshot-create <some_running_vm>"? Thanks in advance. I found the xml files in /var/lib/libvirt/qemu/snapshot/, but hava no idea about the raw snapshot file. Thanks, Lei -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi , I was previously using xen and currently moved to KVM. I am using libvirt to manage these VMs. In den's credit scheduler , I had the ability to set a cap on the cpu usage for a VM. But I was not able to find a similar substitute in KVM. I find that we can use cgroups to provide shares for VM but that will be more like weight based and it doesn't set a hard cap for that VM. I tried

Hi all, Do you have any idea about this error? virsh # dumpxml csg01win7test > domain.xml error: unexpected data '>' Regards, Allen 2014-10-28 Allen Qiu

I have a .cfg configuration file for a xen virtual machine. I need to convert it in xml format to use with libvirt. So I run virsh domxml-from-native xen-xm backupsrv.cfg but I have an error: error: Unknown failure. How can I investigate about the error?

I've created a very basic snapshot XML file, to allow for a description of the snapshot. However when running the virsh command, it doesn't like the formatting. # virsh snapshot-create proxy_0 /vmstore/proxy_0/proxy_0_ss.xml error: XML description for failed to parse snapshot xml document is not well formed or invalid This are the XML file contents... # cat proxy_0_ss.xml

Hey When I want to take a snapshot for a Domain by using virDomainSnapshotCreateXML.

What does this mean? Will I loose anything if - for example - there is not enough space on

Good afternoon guys, I created the VM from XML dump, # virsh create vm4.xml and # virsh list I can see the VM running, and I know the ip address for the VM, but how can I know the username and password to login the running VM, which is created from XML dump? is there any place to edit and add the username and password in guest domain XML ? thanks a lot!! Best, Yuanzhen

Hello, I am using "virsh snapshot-create-as" to create external snapshots of running VMs using libvirt 1.0.2 on Ubuntu 12.04 and libvirt 1.2.2 on Ubuntu 14.04. This works well for creating the snapshots, but I notice that the on-disk XML file in /etc/libvirt/qemu is not updated with the new disk image file after the snapshot is created. This appears to be very similar to

Sorry for the lack of information, my bad. The snapshot is an internal one and the machine is running. The whole thing was set-up by another person and left to me to cope with. The typo is mine, as the machine is isolated I cannot actually copy-paste it so have to do it in the traditional way. I am aware of the issue which come when changing HW but I couldn't do otherwise. I am only

Hi everybody, like in the subject: is there a way for telling libvirt to auto define an xml under /etc/libvirt/qemu? I mean, sometimes it happens to have the /etc/libvirt/qemu shared between nodes, say with a NFS share, since I can set a new xml on a node and I want o see the virtual machine on all the others, is there a way to automate this or am I obligated to launch virsh define <xml> on
