[BUG 2.6.32.y] Broken PV migration between hosts with different uptime, non-monotonic time?
Hello,
I encountered the following bug when migrating a Linux-2.6.32.54 PV domain on
Xen-3.4.3 between different hosts, whose uptime differs by several minutes (3
hosts, each ~5 minutes apart): When migrating from a host with lower uptime
to a host with higher uptime, the VM looses it''s network connection for some
time and then continues after some minutes (roughly equivalent to the

Clarification about virsh migration options
I am trying to work out what all the options are for migrating a KVM
machine to another KVM machine, without using shared storage. The
documentation is not quite verbose and not intuitive, so I'm hoping
someone can explain this to me. The man pages show this syntax:
migrate optional --live --p2p --direct --tunnelled --persistent
--undefinesource --suspend --copy-storage-all --copy-storage-inc

Host information from libvirt KVM/Xen
Hi,
I'm able to get the CPU utilization metrics from libvirt for the guests (VM's) remotely . Is it possible to get the Host Cpu stat's through libvirt ?
I didn't find any information regarding the host cpu cycles and memory utilization to collect them remotely. Libvirt is installed on all the hosts.

Usual number of guests on a host
Hi,
Can someone tell us what is the usual number of guests on a typical host in a production environment ? Has someone tested this ? What number does it scale to ? We have around 150 per host running fine.

qemu:///system and qemu:///session
Hi,
I try to connect from virsh -c qemu:///session and it shows the VMs
created by by that particular user (testuser). But when i try from root
virsh -c qemu:///system i don't see the vms created by testuser. How do i
make it appear in the root's virsh ie the vms created by testuser ?
I need this because i need information for global VM statistics created by
all users.

Re: Determine ongoing shutdown via libvirt or preventing migrations to host
Hi Daniel,
Thank you for your reply. I agree that runlevel is not directly related
to VM management so it is OK, that it is not implemented in libvirt
library. What about prevention of VM migrations, is it acceptable to
just close migration port in firewall ?
Thank you

unhelpful error message on failed "virsh migrate"
Hello,
I have two servers where I can push VMs from one to the other by issuing
the command
virsh migrate --live --persistent --copy-storage-all --verbose \
test6 qemu+ssh://kvmhost2/system
on kvmhost1. I can get the VM back by issuing the equivalent command on
kvmhost2:

Re: Live Migration Issue
Sorry, ctrl entered.
I'm hoping someone here can help me figure out what's going on here.
I've got two CentOS 7 hosts with shared storage that I'm trying to do live
migrations between and I'm running into an error with VMs that were
originally created on a CentOS 6 host and then moved the CentOS 7 hosts.
The CentOS 6 VM runs fine on the host, and can do non-live

[libvirt] virDomainMemoryStats call
Hi,
Is the array mstats returned by virDomainMemoryStats call cummulative or snapshot of the counter at that particular time ? I was of the opinion that is cummulative like the /proc counters but this counter seems to go backwards ie next snapshot value is less than the current one which makes me think these are snapshot values . I'm using RHEL 6.3 libvirt version 0.9.10.

Same host migration
Hi,
I have been selected for GSoC'19 under qemu and was
trying out migration of the pvrdma device.
For my current task, I need to perform a "null" migration
i.e. migrate the VM to the same host for testing purpose.
I am using libvirt 5.1.0 on Fedora 30.
>From what I know, libvirt does not allow this type of
migration by default.

Determine ongoing shutdown via libvirt or preventing migrations to host
Hi list,
Is there any function in libvirt to determine runlevel of host or any
possibility to prevent VM migrations to that host ?
I'm developing simple cluster of 4 servers running KVM VMs. For
management I decided to use python-libvirt. It is working in that way,
that every VM is diskless and booting via PXE so I can run it on every
host server. Every VM has assigned one host as
