2.3. Enabling virtualization on ARM 64
To set up a KVM hypervisor for creating virtual machines (VMs) on an ARM 64 system running RHEL 9, follow the instructions below.
Virtualization on ARM 64 is only provided as a Technology Preview on RHEL 9, and is therefore unsupported.
Conditions préalables
The following minimum system resources are available:
- 6 GB free disk space for the host, plus another 6 GB for each intended guest.
- 4 GB of RAM for the host, plus another 4 GB for each intended guest.
Procédure
Install the virtualization packages:
# dnf install qemu-kvm libvirt virt-installStart the virtualization services:
# for drv in qemu network nodedev nwfilter secret storage interface; do systemctl start virt${drv}d{,-ro,-admin}.socket; done
Vérification
Verify that your system is prepared to be a virtualization host:
# virt-host-validate [...] QEMU: Checking if device /dev/vhost-net exists : PASS QEMU: Checking if device /dev/net/tun exists : PASS QEMU: Checking for cgroup 'memory' controller support : PASS QEMU: Checking for cgroup 'memory' controller mount-point : PASS [...] QEMU: Checking for cgroup 'blkio' controller support : PASS QEMU: Checking for cgroup 'blkio' controller mount-point : PASS QEMU: Checking if IOMMU is enabled by kernel : WARN (Unknown if this platform has IOMMU support)If all virt-host-validate checks return a
PASSvalue, your system is prepared for creating virtual machines.If any of the checks return a
FAILvalue, follow the displayed instructions to fix the problem.If any of the checks return a
WARNvalue, consider following the displayed instructions to improve virtualization capabilities.
Résolution de problèmes
If KVM virtualization is not supported by your host CPU, virt-host-validate generates the following output:
QEMU: Checking for hardware virtualization: FAIL (Only emulated CPUs are available, performance will be significantly limited)
However, VMs on such a host system will fail to boot, rather than have performance problems.
To work around this, you can change the
<domain type>value in the XML configuration of the VM toqemu. Note, however, that Red Hat does not support VMs that use theqemudomain type, and setting this is highly discouraged in production environments.
