Qemu domains have that ability, via an XML namespace that adds <qemu:commandline>: http://libvirt.org/drvqemu.html#qemucommand but no one has yet implemented that for Xen domains. If you want to add it, the src/qemu code would be the obvious starting point to copy from. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

Hello, I have a custom QEMU which requires some non-standard command line arguments to launch a VM. e.g., "--proc-type=secondary" option is always required to launch a QEMU VM. To launch the VM through libvirt (virsh) "How do I specify these non-standard options in XML? OR if thats not possible ,Can you guide me at which point (code file) libvirt converts the XML to QEMU command

Hi Team, I am exploring "edu" device in QEMU to add my own custom device. I am able to add the device using the command line. Would it be possible to add the device using XML file through libvirt? -- Regards, Bharath

Hi all, I am running KVM on a 3.18 kernel. The system runs and Atom processor with 2Gb RAM. Using KVM you obviously can over allocate your resources: say you have 4 guests each configured with 1GB ram. Running all four at the same time, depending on the workload, can crash the system - I get a kernel trace when this happens. But let's consider a simpler case: one guest with 1.5 Gb RAM,

Hi, I tried to enable virtio-blk data plane feature for VMs in my openstack environment, the hypervisor is ubuntu 14.04, libvirt 1.2.2 and QEMU 2.0. As nova doesn't support that parameter yet, I did belows 1. nova boot a VM with raw disk image. 2. nova stop the VM. 3. run "virsh edit <instance-id>" on the hyprvisor node, and adding below into instance xml just before

hi, I use xl toolstack to manage vms on a Xen machine, and also pass some custom parameters when creating a vm, for example: xl create vm.cfg ' param="xyz" ' I am moving to libvirt for vm management. How I can pass those extra parameters using libvirt? Thanks.

...e, use -mem-prealloc. Either you can passthrough it onto qemu commandline [1] or use locked memoryBacking [2]. I advocate for the latter though. Not only it will allocate all the memory at qemu startup it will also lock it so it won't get swapped off.

Hi, I am using virsh 0.9.8 My qemu is 1.0 version. I would like to use Ivshmem device from virsh command line. It is possible to use ivshmem device from qemu command line.But its not working if I am giving -device ivshmem device in xml config file. Does virsh support ivshmem device.?? -- Mrugani Kurtadikar Btech IT College of Engineering, Pune. -------------- next part -------------- An HTML

Hello All, I want to use shared memory , but in virsh I am unable to provide the necessary options for use of shared memory. I want to have some scripts so that they can be included in the xml file so that each time the need is of shared memory , it can be directly used from there only.
