Unexplained shutdown of VM on upgrade of libvirt package
I am running KVM on Centos 6.3 and am seeing an unexplained shut down of two guests. The libvirt package was upgraded to libvirt-0.10.2-18.el6_4.4.x86_64 at the time of the shutdown. Only the two guests shown below was affected, while 9 others running on the same hypervisor were not. Can some one help me to find the cause please ? Regards Chandana GUEST #1 ======== 2013-04-10

I am trying to connect a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out.

Unable to use more than 4 serial devices at once.
Hi All. I'm trying to setup a guest within my hypervisor that acts as a Console Server, using 10 USB to Serial adapters. The Host is all setup and can access each Serial Port without problems. I have attempted to add the Serial Connections to a Guest, using both Virtual Machine Manager and by editing the .XML file, and I can add up to 4 Serial devices (Including one for console access to the

hardware error 0x80000021 on Ubuntu 12.10, need advice
Hi, On a DELL r610 (Intel Xeon L5520) and a Windows guest I have an hardware error. The bug is well known[1][2] and seems fixed with the package 3.5.0-16-generic. But I use 3.5.0-30-generic. Do I need to upgrade to 13.10? Or just the kernel ? Or modify the options of the kvm module? Thanks. [1] https://bugzilla.redhat.com/show_bug.cgi?id=854983 [2]

Slow network performance issues
Hi, I have a fedora21 system that's been running fine under normal network activity, but trying to perform a full backup of the 300GB filesystem is taking forever because the network speed appears to be very slow. Using rsync, the transfer speeds reach a max of like 180kB/s. Using rsync to copy files on the local filesystem is greater than 55MB/s, so I don't think it's a disk

Does libvirt check MCS labels during hot-add disk image ?
Libvirt doesn't care about security during hot add disk images. It even accepts addition of disk images of other guest running on the host. Steps followed to create this scenario : Started two VMs with following security configurations: vm1: <seclabel type='dynamic' model='selinux' relabel='yes'>
