similar to: How to create a guest os from existing disk image file

Hi I have configured KVM with Fedora Core 13 by enabling the KVM virtualization option while installing OS. I have successfully created the guest OS by using the virt-install API /usr/sbin/virt-install --name centos5 --ram 512 --disk path=/var/lib/libvirt/images/ centos.img,size=5 --network network:default --accelerate --vnc -c /tmp/CentOS-5.3-i386-bin-DVD.iso Os installed successfully and after

Hi I have installed libguestfs in Fedora Core 13. Here's the packages I ve installed. [root at kvmcluster ~]# rpm -qa | grep guest guestfish-1.2.2-1.fc13.i686 perl-libguestfs-1.2.2-1.fc13.i686 libguestfs-1.2.2-1.fc13.i686 libguestfs-tools-1.2.2-1.fc13.i686 And I have tried to resize the KVM guest image with virt-resize command. But I'm getting the error as "virt-resize: sorry this

libvirt version: 3.4.0 architecture: x86_64 ubuntu16.04-server hypervisor: kvm,qemu When migrate vm, I encounter error: "Migrate VM virt21 failed unsupported configuration: Unable to find security driver for model apparmor" but two host are same environment.before this error, migrate can be success. the source host seclabel configure is this : <seclabel type='dynamic'

I have a very strange issue that has plagued our KVM-based hypervisor infrastructure. Environment: - All EL7-based libvirt releases since EL7.0 - Fully patched EL7-based KVM guest on a fully patched EL7-based KVM host. - Secondary disk attached via 'virsh attach-device guest /vm/guest-with-secondary-disk-01/disk2.xml --persistent' (note --persistent flag here) Problem Description: -

Libvirt doesn't care about security during hot add disk images. It even accepts addition of disk images of other guest running on the host. Steps followed to create this scenario : Started two VMs with following security configurations: vm1: <seclabel type='dynamic' model='selinux' relabel='yes'>

I am trying to work my way up the learning curve through a forest of conflicting and mostly non-working examples and help pages spread about the internet. I have had no trouble getting a basic vm to build and to then start it up. But I have utterly failed to gain access to the machine. The only host I have available that can run it is a remote server. I have not got the networking side working

Hi, I'm trying to add a channel on a Openstack instance via this command : # virsh attach-device instance-00000005 test.xml that returns this error error: Failed to attach device from test.xml error: internal error: no virtio-serial controllers are available # # cat test.xml : <channel type='unix'> <source mode='bind'

Hi Dominik, Sure, I beleive you can improve using: <cpu mode='host-passthrough'> </cpu> add io='native' <driver name='qemu' type='qcow2' cache='none' io='native'/> After that, please try again, but I can see other thing, for example, change the hda=IDE to virtio.
