Running converted virtualized guests

23.3. Running converted virtualized guests
On successful completion, virt-v2v will create a new libvirt domain for the converted virtualized
guest with the same name as the original virtualized guest. It can be started as usual using libvirt tools,
for example virt-manager.
Guest network configuration
virt-v2v cannot currently reconfigure a guest's network configuration. If the converted guest is not
connected to the same subnet as the source, its network configuration may have to be updated.
23.4. Configuration changes
As well as configuring libvirt appropriately, virt-v2v will make certain changes to a guest to enable
it to run on a KVM hypervisor either with or without virtio drivers. These changes are specific to
the guest operating system. The details specified here pertain to supported Red Hat based Linux
distributions and Windows.
23.4.1. Configuration changes for Linux virtualized guests
Table 23.1. virt-v2v changes to Linux virtualized guests
Change Description
Kernel Un-bootable, that is, xen para-virtualized, kernels
will be uninstalled. No new kernel will be installed
if there is a remaining kernel which supports
virtio. If no remaining kernel supports virtio and
the configuration file specifies a new kernel it will
be installed and configured as the default.
X reconfiguration If the guest has X configured, its display driver
will be updated. See GUEST DRIVERS for which
driver will be used.
Rename block devices If changes have caused block devices to change
name, these changes will be reflected in /etc/
fstab
Configure device drivers Whether virtio or non-virtio drivers are
configured, virt-v2v will ensure that the correct
network and block drivers are specified in the
modprobe configuration.
initrd virt-v2v will ensure that the initrd for the default
kernel supports booting the root device, whether
it is using virtio or not.
SELinux virt-v2v will initiate a relabel of the guest on the
next boot. This ensures that any changes it has
made are correctly labeled according to the
guest's local policy.
virt-v2v will configure the following drivers in a Linux guest:
