Hi, I'm using virsh to instance a VM in my environment, but I'm running on some issues. I created the following domain file: <domain type='kvm'> <name>demovm</name> <uuid>4a9b3f53-fa2a-47f3-a757-dd87720d9d1d</uuid> <memory unit='KiB'>4194304</memory> <currentMemory

Hi,all,i build qemu-kvm1.0.93 from source code on centos6.2 , # qemu-system-x86_64 --version QEMU emulator version 1.0.93 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard and the guestfish's version: # guestfish --version guestfish 1.7.17 but when i use the guestfish command to upload a file to a vm,it does not work , # guestfish --rw -i -d centosvm upload /test/ifcfg-eth0_centos

Hi, Is there a way to backup KVM Guest VM running CentOS Linux release 7.9.2009 (Core) OS in kvmguestosimage.ova or kvmguestosimage.vmdk format as I am trying to restore it in AWS by referring to https://aws.amazon.com/ec2/vm-import/ article as per the below supported file format.

I have a kvm guest running MS-WinV7 on a CentOS-6.5 host. The WinV7 guest was installed from a CD. It installed correctly and was updated and added to an MS Active Domain without difficulty. I was able to do work on it through the virt-manager console and I was able to shut the system down from the console without problem. I cannot get it to restart however. virsh start

Hi all, I got bored and implemented SCSI passthrough for the virtio-blk driver. Principle is quite simple, just put the missing fields (cdb, sense and status header) on the virtio queue and then call the SG_IO ioctl on the host. So when using '-drive file=/dev/sgXX,if=virtio,format=host_device' you can happily call any sg_XX command on the resulting vdX device. Quite neat, methinks. And

Dear All, While trying to run kvm VM using vmdk disk on 6.4 , I got into the following error, error: Failed to create domain from vmdkvm.xml error: internal error process exited while connecting to monitor: qemu-kvm: -drive file=/mnt/vmdkTOKVM/vmdkTOKVM.vmdk,if=none,id=drive-ide0-0-0,format=vmdk,cache=none: 'vmdk' invalid format upon further digging I came across this thread (

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'

Here is v11. Fixed comments/bugs and updated against the latest libvirt.git. Changes v10->v11: - fixed comments on each patches - fixed cgroup handling in patch 3. - fixed MODIFY_CURRENT handling in patch 4. most of diff comes from refactoring qemu/qemu_driver.c -- conf/domain_conf.c | 40 ++ conf/domain_conf.h | 5 libvirt_private.syms | 3 qemu/qemu_driver.c | 727

Hi everyone, I have a question on connecting to hardware devices. With virt- manager I am attempting to use a hardware cdrom/dvd drive from an Ubuntu 16.04 VM however, i keep getting "'host_cdrom' is not whitelisted" errors when starting the VM. After some searching I checked my processor and realized it does not support VT-d. Is this 1) a requirement for sharing the device with

Hi All, Scientific Linux 7.2 I am drawing a blank on Google here. I am, trying to boot a qemu-kvm virtual machine off of /dev/sr0 (my DVD). But I get the following error Error starting domain: internal error: qemu unexpectedly closed the monitor: 2016-12-22T00:00:30.330333Z qemu-kvm: -drive file=/dev/sr0,format=raw,if=none,media=cdrom, id=drive-sata0-0-0,readonly=on:

Does libvirt (will) support qemu's userspace vhost scsi and blk?
