After saving a particular VM running WinXP, any attempt to resume it (even when no other VM's are running) generates the following error: olympus ~ # virsh restore /var/lib/libvirt/qemu/save/WinXP.save error: Failed to restore domain from /var/lib/libvirt/qemu/save/WinXP.save error: internal error: Failed to reserve port 5908 This started sometimes towards the end of last year with only the

Hi, I am running OpenStack Cluster and use libvirt + cgroup to limit vm’s performance https://wiki.openstack.org/InstanceResourceQuota What I am confusing is.. 1. After running a vm instance with some croup limit applied, I can’t find any related cgroup settings. 2. Can I change limit value after instance is running? like change disk_read_iops_sec from 10 to 20. One of the xml file like below.

Hi, I have a fedora27 system with a win10 guest trying to use photoshop 2015. I've adjusted the vram parameter for the guest to 512M with QXL, but photoshop still reports "3D features and some filters require 512MB vRAM and photoshop has detected less than that on your system." What is the proper way to adjust the vram value to provide at least 512MB vram? I've included my xml

Hi, I've got two hosts. Most of my guests are Windows systems. I'm using LANBench to test network performance. 1) From an physical PC to a guest (it doesn't matter on which host), I get almost 1Gb/s. They are connected through a 1Gb/s swich => very good! 2) From a guest on one host to a guest on the other host => plusminus 1Gb/s => Okay! 3) Between two guests on the same

Hello, Hope all is well. I've been looking at how I can create a virtual machine which is NUMA capable. I was able to do that by: 140 <qemu:commandline> 143 <qemu:arg value='-numa'/> 144 <qemu:arg value='node'/> 145 <qemu:arg value='-numa'/> 146 <qemu:arg value='node'/> 147 </qemu:commandline> This

Hi, I was trying to follow this guide (http://libvirt.org/compiling.html) to compile libvirt1.2.7 on CentOS6.4. There is an error on executing "make". Below is the steps to reproduce and the error messages. Any help is appreciated. Thanks. $ sudo yum install gcc make gnutls-devel device-mapper-devel \ python-devel libnl-devel yajl-devel \ libxml2-devel libpciaccess-devel $ wget

I would really appreciate some pointers on what I am doing wrong here. I have a need to run multiple virtual guests which have each their own GPU and some USB controllers passed-through. I am able to run one of the guests like this (assuming vfio stuff has happened elsewhere), but I would prefer to use virsh: kvm -M q35 -m 8192 -cpu host,kvm=off \ -smp 4,sockets=1,cores=4,threads=1 \ -bios

I just ran into a problem I can't make heads or tails of, so I'm hoping to get some help here. I have a custom built Embedded Linux running qemu-kvm 1.1.2 and libvirt 1.2.20 I'm creating a domain with the following config: <domain type='kvm'> <name>myVM</name> <memory unit='KiB'>2097152</memory> <vcpu

Using: edk2.git-0-20150803.b1141.ga0973dc.x86_64 edk2.git-ovmf-x64-0-20150802.b1139.gb234418.noarch On Fedora 22. Provisioning a i440FX system in virt-manager and attempting to boot results in successful EFI initialization, but the VM exits ungracefully after the bootloader (with F22 and CentOS 7 installer images). There's no really useful information in any of the logs. Using qemu-kvm

Hi, I'm investigating a performance issue on a virtualized windows server host that is run on a ubuntu machine via libvirt/qemu. While the host can easily read/write on the raid drive with 100Mmb/s as observable with dd, the virtualized windows server running on that host is barely able to read/write with at most 8Mb/s and averages around 1.4Mb/s. This has grown to the extent that the

Hello, I've setup a VM with default networking (NAT) and this works fine but hosts on my LAN can't get to the VM since it uses NAT. When I try to set network to use MacVTap with either default or bridged I get no networking for the VM. Any hints around this? I would like to have the VM's on the same LAN as my host and other machines. I don't care if the VM host can't reach the
