I wanted to add “-qmp tcp:127.0.0.1:1235” when creating VM because I was using a multi-level debugger which needs this option to get more information of the VM

Is there any way to get virsh / libvirt to create a domain such that I can later connect to it via QMP (without hacking the code)? The command line that libvirt creates for my current setup looks like this: /usr/local/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name winxpsp2 -uuid ab244939-c804-1aff-68b6-9324f174c3c8 -nodefconfig -nodefaults

Hi All, I am running on CentOS Released 6.1 final. Been using and running Linux KVM quite well for quite some time, something goes wrong after I perform yum upgrade. I created new VM yesterday without any problem, same exact installation procedure, installed FreeBSD 8.2. I tried to create a new VM today after yum upgrade, it's able to detect the hard disk, when I start commit FreeBSD 8.2

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

Greetings - I shutdown one of my Centos 6.2 VMs for some offline maintenance and am now unable to get it to restart. I am also unable to create and start a new VM. The host system is Centos 6.2, fully up to date. I have been searching Google for two days and have not been successful in getting a VM to start. I have restarted libvirtd, but did not want to shutdown my other two running VMs and

Hi there, I have used qemu to install FreeBSD 9.2 release, and i can boot it fine with: $ qemu-system-x86_64 -hda images/FreeBSD-9.2-RELEASE-amd64.img I then made virsh aware of my brand new VM (see attached XML), but when i run it via virsh, It hangs after the bootloader whith this message: Booting... CPU doesn't support long mode From the log, here is the generated qemu command:

Greetings, I have two machines running the same distro, both running qemu 5.1.0, one runs libvirt 6.7.0, the other 6.8.0. I've decided to test the viability of passing through my sata cdrom into a vm, so I went to the libvirt docs, read a bit and added the following to a debian10 uefi vm running on libvirt 6.8.0: <controller type='scsi' index='0'

Hi, When I'm trying to run qemu-kvm command on RHEL6(linux kernel 2.6.32) then I get following errors which I think related to tap devices in my setup. Any idea why is that? bash$ LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none /usr/libexec/qemu-kvm -S -M rhel6.2.0 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name instance-00000027 -uuid

Hello, I am running into issues restoring VMs during reboot for some of my XP VMs - the environment is QEMU 2.2.0, libvirt 1.2.12 on CentOS 6.5 with KVM and libvirt-guests is set to suspend at shutdown. The weird part is Windows 7 is restored properly from the managedsave however XP does not, doing a start from virsh shows this: virsh # start xp-check error: Failed to start domain xp-check

Hello, I use libvirt 3.3.0 and qemu 2.9.0 My domain XML spec is the following: <domain type='qemu'> <name>s390_generic</name> <uuid>82b4d16e-b636-447e-9fda-41d44616bce8</uuid> <memory unit='KiB'>1048576</memory> <currentMemory unit='KiB'>1048576</currentMemory> <vcpu

Hi! I am trying to setup a guest using virt-install script: /usr/bin/virt-install -n fc18guest5 -r 1024 \ --disk path=/home/aik/virtimg/fc18guest,size=8 \ -c /home/aik/virtimg/Fedora-18-ppc64-DVD.iso \ --video vga --arch=ppc64 -d --machine=pseries And it fails. I could not find any relevant log in /var/log/libvirt/ so I simply hacked /usr/local/bin/qemu-system-ppc64 to print all the
