Supported Environments

VMware version

• VMware vSphere ESXi 7.0.x

OpenStack distributions

Guest VMs

[1] SUSE Enterprise Linux guests are validated to run on RHEL hosts. However, SUSE Linux uses the btrfs file system by default, which is unsupported by RHEL. Therefore, converting a SUSE system that use btrfs is not possible with virt-v2v.

In addition, VMs that use X graphics and a SUSE Linux Enterprise Server 11 operating system should be re-adjusted after the conversion for the graphics to work properly. To do so, use the sax2 distribution tool in the guest OS after the migration is finished.

[2] As a Technology Preview, converting Debian and Ubuntu VMs is not supported. In addition, this conversion currently has the following known issues: * virt-v2v cannot change the default kernel in the GRUB2 configuration, and the kernel configured in the VM is not changed during the conversion, even if a more optimal version of the kernel is available on the VM. * After converting a linux virtual machine to KVM, the name of the VM's network interface may change, and thus requires manual configuration.

Note: virt-v2v conversions of any operating system not listed above may in some cases work, but are not supported by Red Hat.
