similar to: Reg: Adding "edu" device using XML file

Hello Han, Thanks for the response. The XML option with qemu:commandline works if the device is added during the VM creation. But I would like to hot-plug the device to the running VM. I can add the device using the command line <virsh qemu-monitor-command --hmp VM-Name device_add edu,id=edu0> But I would like to add the device using the XML file, like <virsh attach-device VM-Name

Hi Team, I am doing a small testing and I don't know if my expectation is correct or not. Pardon me if I am ignorant. I created a VM and the VM is running. In the hypervisor I have created ".img" file and attached this .img file to the VM. My expectation is that, if VM is writing files to the attached disk, then it should reflect in the .img file created in the hypervisor. But It is

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 using QEMU/KVM for launching VMs and libvirt to govern those VMs. I would like to synchronise the connection tracking entries specific to the VM during the VM LIVE migrations. It is required when the firewall is implemented at the host level like libvirt's "network filters". If stateful firewall is enabled, then unless these connection tracking entries are

For the libvirt 5.8 release, I find that there is a new comment in qemu.conf: #slirp_helper = "/usr/bin/slirp-helper" It indicates that there is a slirp-helper to help setup slirp network. But I cannot find it even after I built the latest qemu(v4.1.0-1378-g98b2e3c9ab) and libvirt (v5.9.0-rc1-2-g73f91d659b). Could you please tell me where I can find that helper program? Thanks --

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 Eric, Thanks! You are right, I missed declaring namespace, now, the <qemu:commandline> is saved after virsh edit. However, both namespace and <qemu:commandline> tag are lost after I run "nova start" to launch the VM. Any idea that how could I make this qemu command take effect ? Regards, CY.

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.
