yes, I got your point, thanks very much Eric. If I want to take a distributed snapshot, which need pause all the VMs and then take snapshot, how can I control the pause for all the VMs? Is there only way that I turn to freeze/thaw functions? and freeze/thaw only for file systems, not for the whole guest, am I right? Thanks a lot!

Thanks very much Eric! This is exactly what I guessed, I just wondering where I could find this piece of code and control the the pause time of guest, while the snapshot being taken? thanks !

Hello folks, If I give command to take external disk-only live snapshot, such as # virsh snapshot-create-as vm1 snapshot_vm1 --disk-only will the guest OS be paused or suspend while the snapshot being taken? Thanks very much! Best, Yuanzhen

Thank you Eric, I am using KVM: qemu.. I'll try to see how I can use qemu-guest-agent.. If you have links to examples on how to start with it let me know please. Consider the following simple scenario.. I am using KVM to run several VMs; one of OSs in the guests is Windows XP. I want to send to it something from the Hypervisor level, e,g text,parameters,etc so that it will be displayed in

Hello Yesterday, i brought linksys PAP2 and have success with that. The only thing that does not go well is the music on hold. When i press 'hold' button from the telephone set instead of playing the music on hold that i have setup in Asterisk, Telephone Set plays its own MOH. Is there any way to tackle this issue. Regards Taimur Hasan -THQ- !!!ONE

Hello, I'm using libvirt and sanlock on qemu-kvm guests. Each guest has it's own Logical Volume for it's root filesystem. Sanlock is configured and working and prevents me from starting the same VM twice on multiple nodes and corrupting it's root filesystem. Each VM's domain XML resides on 2 servers that share the LVM volume group over fiber channel. In testing, I noticed

Hi, when a normally running VM is migrated, libvirt sends VIR_DOMAIN_EVENT_RESUMED_MIGRATED event on the destination once the migration completes. I can see that when a paused VM is migrated, libvirt sends VIR_DOMAIN_EVENT_SUSPENDED_PAUSED instead. Since there seems to be nothing migration specific about VIR_DOMAIN_EVENT_SUSPENDED_PAUSED event, my question is: Is it safe to assume on the

You mean, you have multiple VMs, and want to take a snapshot of all their storage at the same point in

The guest will temporarily pause, but the time that it remains paused will be a fraction of a second. In practice,

Hey all! I'm trying to do a bit of logic here so that a user only has to dial one code to pause/unpause in a queue (e.g. *0 will (un)pause depending on the users's state). My logic looks fine to me but every time ${PQMSTATUS} shows up empty. Here's the extensions.conf part.... exten => *0,1,NoOp(${PQMSTATUS}) exten => *0,n,Macro(user-callerid,SKIPTTL,) exten =>

Hi, I'm using libvirt(1.0.0) with python, for managing virtual machines.. but while taking multiple snapshot domain is crashing... Snapshot XML ------------------------- <domainsnapshot> <name>snp1</name> <creationTime></creationTime> <description>Description</description> <state></state> <domain>

Hi all, I use gluster 3.12 on centos 7. I am writing a snapshot program for my geo-replicated cluster. Now when I started to run tests with my application I have found a very strange behavior regarding geo-replication in gluster. I have setup my geo-replication according to the docs: http://docs.gluster.org/en/latest/Administrator%20Guide/Geo%20Replication/ Both master and slave clusters are

Hi, Thanks for reporting the issue. This seems to be a bug. Could you please raise a bug at https://bugzilla.redhat.com/ under community/glusterfs ? We will take a look at it and fix it.

Actually, for new enough qemu (one with the 'transaction' QMP command), or for a guest

Hi All, I'm at the end of my tether here and would really appreciate some help. I'm trying to implement DTMF based pause/resume of call recording. I'm using Asterisk 1.4.22.1. Here's the scenario: The caller (SIP or ISDN, doesn't matter) dials into the asterisk which executes the following code: exten => _X.,1,Monitor(wav,${CALLDIR}${UNIQUEID},mb)

Hi there, I am a beginner with Libvirt. I was practicing using Python bindings with libvirt to do some basic stuff like starting a VM, rebooting a VM, displaying the number of domain,etc. I was wondering since the hypervisor has control over the VMs, it is possible to use Libvirt to inject code into the VM? Is it possible to start processes inside a particular VM using the Libvirt API. If not,

Two things: 1. I''m not convinced ''xm crash'' is needed - ''xm destroy'' will do this (and if you want a dump, do ''xm dump'' followed by ''xm destroy'') 2. I don''t see the point of the --noreboot option on ''xm dump'' -- I think this command should simply live-dump the specified domain - as
