hi alll.. i want to find the xen domain''s state using xm domstate command, domstate command works fine inside virish but when i try with xm like [xm domestate VM_NAME] its giving an error saying subcomand domestate not found. i just want to shutoff the xen virtual domains using a scrip to take backup. so i just want to make sure that the domain are shutdown successfully after

I am trying that out. Debian 9 (stretch) backports still doesn't have 4.16 kernel. So I building the kernel from the source. Will keep you posted. On Mon, 26 Mar 2018 at 13:00 Richard W.M.

Hi All, I am unable to figure out the issue here, when I try to create a filesystem (ext4) on a virtual disk using qemu-nbd. This happens intermittently. Following is the sequence of commands:- $> qemu-img create -f qcow2 test.qcow2 30G $> qemu-nbd --connect=/dev/nbd0 test.qcow2 $> *mkfs.ext4 /dev/nbd0* * mkfs.ext4: Device size reported to be zero. Invalid partition specified, or*

Thanks. Reading the defect and the associated thread in https://bugs.launchpad.net/qemu/+bug/1661386, I enabled performance counters in VMWare guest settings. Now the kvm assertion `ret == cpu->kvm_msr_buf->nmsrs' is gone. But the qemu/kvm hangs after printing "SeaBIOS (version 1.10.2-1)" I presume this too is a qemu/kvm issue for vmware platforms. Is there any existing issue

Hi, I would like to get a clear picture on external snapshots memory dump ( i.e. system-checkpoint) vs dumping the memory of the guest. I have created external snapshots which produces a disk file and a memory file. I am not able to use this memory file in any memory analysis tools, for instance volatility. However, the memory dump taken through "virsh dump" works just fine with such

I am using a debian 9 guest, hosted on a ESXi platform with nested virtualisation enabled. On this debian 9 guest when I run libguesfs-test-tool, it fails with an error: "qemu-system-x86_64: /build/qemu-DqynNa/qemu-2.8+dfsg/target-i386/kvm.c:1805: kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed." Instead when I use a wrapper script and hook it with the env

Thanks a lot for the detailed explanation. Currently I am taking a dump of the memory with the virsh dump ‘live’ flag and taking the snapshot with the memory file pointed to /dev/null, without even pausing the guest. I don’t have a use case to restore from the snapshot snapshot so hopefully this approach will not cause any issue. On Mon, 26 Nov 2018 at 5:23 PM, Peter Krempa

Hi. I've set up a Debian6+Xen4+libvirt0.9 server. VMs are going to be managed by PaceMaker with VirtualDomain primitive. As found on some mailing list I've set export VIRSH_DEFAULT_CONNECT_URI="xen:///" in root's .bashrc, but when I run virsh commands, it takes up to 10s to get the result! Is this normal? At some point today I had issues connecting to libvirt, and in this

Hi Libvirt, Is there a command that performs the same operation as blockpull while a domain is shutoff? I have a backing chain base <-- A <-- B that I would like to shorten to base <-- B It seems like blockpull B, setting --base <path-to-base> does this, but only when the domain is running. Thanks!

Hi all, I've got a weird issue, and I'm trying to confirm if it's a bug, and if so, if there is a workaround until it is fixed. The situation is this: If I virsh reboot <domain> --mode acpi, it will actually reboot the domain cleanly (watching from the console allows me to see the full shutdown messages, followed by a bootup). However, after this point, virsh domstate

Hi all: I am using the libvirt version that comes with Ubuntu 18.04.3 LTS. I want to backup a virtual machine in a foolproof way: - Gracefully shutdown the VM. - Backup the disk image. - Restart the VM. I wrote the following script to do that: https://github.com/rdiez/Tools/blob/master/VirtualMachineManager/BackupVm.sh Writing that script was difficult enough because of the virsh limitations

Hi all, I am experiencing some problems with different versions of libvirt (0.7.5 and 0.7.7), with a kvm (WinXP), host running Ubuntu 9.10, and i would like to ask you two questions: - In virsh, after running the command "shutdown domainName", what should be the final state of the domain, if the shutdown finishes correctly: "shutoff", "no-state",

Hello Fairly new to libvirt. I’m hoping to both solve a problem with this question as well as learn more detail about how libvirt works. Using RHEL 6.4 and libvirt version is 0.10.2 and qemu-img version is 0.12.1.2 Using virt-manager I created a VM. Nothing unusual as far as I can see. I then added a disk. So I have a second virtio based volume which the guest then mounts as a separate

The reason given is shut off (crashed). So something virsh backup-begin does is causing he guest to crash?
