Hello, I've running Ubuntu-14.04 as my host and my guest. I've been trying to get guest to host communication set up by configuring a virtio-serial device.

Hello, I want to do a snapshot which the VM has volumes. But I want to skip the volume check when I do the snapshot. (Which means I want to do a snapshot without detaching the volume) So I try to write a snapshot XML refer by http://libvirt.org/formatsnapshot.html as following: vda is my VM basic disk (qcow2) vdb is a volume (raw) ================ t1.xml =============== <domainsnapshot>

Hi I tried to use virsh blkstat to get information of a block, but it returns an error message as shown below This function works fine in KVM, but fail in XEN. I tried XEN 3.4.3 ,4.0.0 and 4.0.1 with libvirt 0.7.1 from fedora yum server and 0.8.1 from libvirt . All of them are fail to get the block status. The following is the config file and error message of virsh domblkstat. Any one

Hello, I installed the last version of Xen (xenserver-core-0.9.0-9.x86_64 from yum) and I'm trying to manage my VMs with virsh. The version that I installed is using the Xapi/xe toolstack. The problem I have is that I'm not seeing the VM that is started with "virsh -c xen:/// list --all". Here is what I have: root# xe vm-list uuid ( RO) :

Thank you, that's it! virsh vol-list storage VM1   /dev/storage/VM1.img VM2   /dev/storage/VM2.img VM3   /dev/storage/VM3.img [dead] VM4   /dev/storage/VM4.img [dead] A last stupid question (I don't want to make a big mistake ...): Is virsh vol-delete VM3 virsh vol-delete VM4 the right command to get rid of the offending ones?

Hi! I was reading the Wiki about 'Live Disk Backup with Active Blockcommit, https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit and see that example shown seems to be using two different names for the same file.

Hi, I''m new to Xen, and am facing issues in the following scenario: (1) Create a paravirtualized domU (installing from SLES10SP2 dvd) using virt-manager. (2) Make a copy (using either "cp" or "dd") of the disk image file used by this domU and rename it. (3) Mount the root partition of this disk image (identified using "kpartx"), change the network related

I have 2 VMs launched by : 'virsh create <xml file>' . Both VMs get 2 vcpus (out of total 2 cores of the host) I then try bias their cpu cycle quota by manipulating the cpu_shares ( virsh schedinfo --set cpu_shares=<value> vm1/2 ) so that VM1 will get 3 times the cpu cycles VM2 gets. (e.g : VM1 cpu_shares = 150 . VM2 cpu_shares = 50) . There are no other VMs defined or

Thanks Kashyap, The command line examples makes thing quite clear :) rsync for image (large) files create a new file for every little change, that was the reason I started looking in to using dirty bitmaps. /Jd On 10/11/14, 1:13 AM, Kashyap Chamarthy wrote: > On Fri, Oct 10, 2014 at 07:32:06PM -0600, Eric Blake wrote: >> On 10/10/2014 11:37 AM, Jd wrote: >>> Hi >>>

Hi Eric. Thank you so much for your quick and relieving answer. Le 2015-09-11 17:05, Eric Blake a écrit : > Yes, using active block-commit is the ideal way to perform a live backup.

Hi and hello, I have a problem confusing me. I hope someone can help me with it. I followed a "best practise" - I think - using dedicated zfs filesystems for my virtual machines. Commands (for completion): [i]zfs create rpool/vms[/i] [i]zfs create rpool/vms/vm1[/i] [i] zfs create -V 10G rpool/vms/vm1/vm1-dsk[/i] This command creates the file system [i]/rpool/vms/vm1/vm1-dsk[/i] and the

Hello, I recently compiled libvirt 1.0.1 and qemu 1.3.0 on Ubuntu 12.04. I have performed live snapshots on VMs using "virsh snapshot-create-as" and then later re-merge the images together using "virsh blockpull". I am wondering how I can do a couple of other operations on the images while the VM is running. For example, VM1 is running from the snap3 image, with the following
