| + | =====Create VM in Proxmox===== | ||
| + | I create a VM in Proxmox with the following specifications: | ||
| + | * Linux 6.x - 2.6 Kernel | ||
| + | * ISO image: custom.iso (created above) | ||
| + | * Machine: q35 | ||
| + | * BIOS: OVMF | ||
| + | * Select preferred datastore in EFI storage | ||
| + | * SCSI Controller: VirtIO SCSI single | ||
| + | * Check Qemu Agent | ||
| + | * Disk size 16 GB | ||
| + | * Cache: Default | ||
| + | * Select Discard | ||
| + | * Sockets: 1 | ||
| + | * Cores: 2 | ||
| + | * Type: x86-64-v2-AES | ||
| + | * Memory: 4096 | ||
| + | * Bridge: vmbr0 | ||
| + | * Model: VirtIO (paravirtualized) | ||
| + | |||
| + | After that convert this VM to a template and when creating a VM make a full-clone of this template. | ||
| + | =====Modify after boot===== | ||
| + | The network is DHCP enabled in this example. The following steps remain: | ||
| + | * Manually confige network with nmcli/nmtui | ||
| + | * Set hostname | ||
| + | |||
| + | =====Resize disk in Proxmox===== | ||
| + | When the template diskspace is too small. Resize it in Proxmox and do the following in the VM: | ||
| + | < | ||
| + | rescan-scsi-bus.sh | ||
| + | growpart /dev/sda 4 | ||
| + | xfs_growfs /var | ||
