interface should automatically come up but can also use |
||||
$ virt-viewer --domain-name mirror |
||||
if vm is on a remote machine |
||||
$ virt-viewer --connect qemu+ssh://user@host.example.com/system vmnamehere |
||||
|
||||
for now just have a folder of screenshots |
||||
- change name of lvm volume from "lv0-root" to just "root" |
||||
troubleshooting: ignore "failed to unmount /cdrom" and just ctrl+c in viewer |
||||
|
||||
login into your created user (from install), change to root, and create password for root |
||||
$ sudo su |
||||
type in your password |
||||
$ passwd |
||||
create root password |
||||
|
||||
create zpool (use /dev/disk/by-id/.. instead) |
||||
$ apt update |
||||
$ apt install zfsutils-linux nginx rsync |
||||
$ mkdir -p /mirror/root/.cscmirror |
||||
$ zpool create -f -m /mirror/root/.cscmirror cscmirror raidz2 /dev/vdc /dev/vdd /dev/vde /dev/vdf |
||||
|
||||
may already be mounted but just to be sure |
||||
$ zfs mount -a |
