Hi, All There is following issue in latest libvirt-4.5.0-10.el7_6.12 package, which could prevent live VM migrations with web sockets enabled, when libvirtd were restarted prior to migration. Environment: # uname -a Linux inv-cp1-hv3-centos7 3.10.0-957.12.2.el7.x86_64 #1 SMP Tue May 14 21:24:32 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux # cat /etc/redhat-release CentOS Linux release 7.6.1810

Then you should definitely submit a bug with redhat about this, seems like a serious one. -- Sent from the Delta quadrant using Borg technology!

Yes, you can. In fact you can use the binaries from the ovirt repo itself, no need to rebuild. -- Sent from the Delta quadrant using Borg technology!

As I can see - bugzilla.redhat.com for oVirt Product does not contain qemu-kvm-ev Component at all - looks like this is yet another bug - in the bugzilla settings. But I can't find how to report

Hello, I want to do comparative study between xen and kvm during live migration of vm.analysis of downtime and also using wireshark and netperf tool to perform analysis, what else can be done? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

Hello, All! Is it possible to use binary packages build from http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7/SRPMS/qemu-kvm-ev-2.1.2-23.el7_1.3.1.src.rpm with plain CentOS 7.1 and use all other packages from CentOS (libvirt, virt-manager, etc) Is it have reasons, if I not use live migrations and qcow2 snapshots? (instead use zfs, zvols and zfs snapshots for VM disks online backups) Is using

In fact - I can't use raw binaries from the ovirt repo itself, because these qemu-kvm binaries contains one bug, which is already fixed in Debian: If you want to migrate Windows from hardware node to VM using CentOS 7.1 on hardware node and

Hello, I am now testing XEN live migration on 3 physical hosts with XEN 4.0.1 pvops Ubuntu 10.10 (2.6.35-22). The kernel is compiled and built with default selections plus the support for ext4 file system as well as the support for network file system server. The three hosts are connected by one D-link gigabit switch (DGS-2205). I find that: 1) If the 3 hosts are booted about the same time, the

Sandro, Could you please enumerate the actual technical differences between stock qemu-kvm and qemu-kvm-ev? For example, what could one do with qemu-kvm-ev that cannot with qemu-kvm?

Hi, I'm thinking about how to go about migrating our Xen VMs to KVM. Migrating the configuraton should be easy using the virsh dumpxml/define commands but what is the best way to transfer the (logical volume based) images without too much downtime for the guest system? Can rsync operate on logical volumes? If so I could potentially use "dd" to transfer an initial copy of the
