xl cria problema com o Arch Linux, Xen, DomU LVM

0

Esta ainda é minha primeira vez configurando um DomU. Com Dom0 sendo o Arch Linux e o DomU também. Eu recentemente descobri que eu precisaria de um LVM para a minha configuração, como eu quero pelo menos duas partições (root + swap).

Meu problema atual é que eu não sei qual deve ser a configuração do meu LVM e o que eu tenho até agora:

$ sudo xl criar /etc/xen/ArkOS-dev_PV.cfg

Parsing config from /etc/xen/ArkOS-dev_PV.cfg
libxl: error: libxl_device.c:283:libxl__device_disk_set_backend: Disk vdev=sda1 failed to stat: vm_volumes/root.ArkOS_Dev: No such file or directory
libxl: info: libxl.c:1691:devices_destroy_cb: forked pid 529 for destroy of domain 3

Meu arquivo de configuração de inicialização do DomU:

$ cat /etc/xen/ArkOS-dev_PV.cfg

name = 'ArkOS_Dev'
kernel = "/mnt/arch/boot/x86_64/vmlinuz"
ramdisk = "/mnt/arch/boot/x86_64/archiso.img"
extra = "archisobasedir=arch archisolabel=ARCH_201511"
memory = 512
disk = [ "phy:vm_volumes/root.ArkOS_Dev,sda1,w",
         "phy:vm_volumes/swap.ArkOS_Dev,sda2,w", 
         "file:/home/xen/ISO/archlinux-2015.11.01-dual.iso,xvdb:cdrom,r" 
       ]
vif = [ 'mac=00:16:3e:49:2b:a1,bridge=xenbr0' ]
root = "/dev/sda1 ro"

$ lsblk -f

Resolvido por isso:

name = 'ArkOS_Dev'
kernel = "/mnt/arch/boot/x86_64/vmlinuz"
ramdisk = "/mnt/arch/boot/x86_64/archiso.img"
extra = "archisobasedir=arch archisolabel=ARCH_201511"
memory = 2048
vcpus = 3
disk = [ "format=raw, vdev=xvda, access=rw, target=/dev/vm_volumes/root.ArkOS_Dev",
         "format=raw, vdev=xvdb, access=rw, target=/dev/vm_volumes/swap.ArkOS_Dev",
         "format=raw, vdev=xvdc, access=ro, devtype=cdrom, target=/home/xen/ISO/archlinux-2015.11.01-dual.iso"
       ]
vif = [ 'mac=00:16:3e:49:2b:a1,bridge=xenbr0' ]
root = "/dev/xvda rw"

Depois de instalar o DomU com isto:

name = 'ArkOS_Dev'
bootloader = "pygrub"
memory = 2048
vcpus = 3
disk = [ "format=raw, vdev=xvda, access=rw, target=/dev/vm_volumes/root.ArkOS_Dev",
         "format=raw, vdev=xvdb, access=rw, target=/dev/vm_volumes/swap.ArkOS_Dev"
       ]
vif = [ 'mac=00:16:3e:49:2b:a1,bridge=xenbr0' ]
root = "/dev/xvda rw"
