# libvirt and KVM
|
||
|
|
|
||
|
|
## Purpose
|
||
|
|
|
||
|
|
The libvirt profile installs QEMU/KVM administration, UEFI firmware, software
|
||
|
|
TPM support, VM creation tools, bridge utilities, and the libvirt daemon. This
|
||
|
|
supports later Linux or Windows 11 VM work without defining guests.
|
||
|
|
|
||
|
|
## Firmware pre-checks
|
||
|
|
|
||
|
|
Confirm CPU virtualization is enabled:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
lscpu | grep -E 'Virtualization|Hypervisor'
|
||
|
|
grep -Eom1 '(vmx|svm)' /proc/cpuinfo
|
||
|
|
```
|
||
|
|
|
||
|
|
IOMMU and GPU passthrough require separate firmware, kernel command-line,
|
||
|
|
device isolation, driver binding, and recovery planning. This toolkit reports
|
||
|
|
hints but does not apply those changes.
|
||
|
|
|
||
|
|
## Validation
|
||
|
|
|
||
|
|
```bash
|
||
|
|
systemctl status libvirtd
|
||
|
|
virsh list --all
|
||
|
|
virsh net-list --all
|
||
|
|
virsh pool-list --all
|
||
|
|
```
|
||
|
|
|
||
|
|
Use `virt-host-validate` when available for a broader host capability report.
|
||
|
|
Desktop use of `virt-manager` requires a graphical environment or remote
|
||
|
|
display strategy.
|
||
|
|
|
||
|
|
## Networking and Windows 11
|
||
|
|
|
||
|
|
The default libvirt NAT network is distinct from host bridge networking. Review
|
||
|
|
DHCP, DNS, forwarding, and firewall behavior before changing it.
|
||
|
|
|
||
|
|
Windows 11 typically needs UEFI and a TPM device. The installed OVMF and swtpm
|
||
|
|
packages provide those building blocks, but guest creation and licensing remain
|
||
|
|
manual.
|
||
|
|
|
||
|
|
## Troubleshooting
|
||
|
|
|
||
|
|
```bash
|
||
|
|
journalctl -u libvirtd
|
||
|
|
virsh net-info default
|
||
|
|
virsh pool-list --all
|
||
|
|
lsmod | grep kvm
|
||
|
|
```
|
||
|
|
|
||
|
|
Disabling `libvirtd` does not remove VM disks or definitions. Package removal
|
||
|
|
and VM data deletion are intentionally outside this toolkit.
