DomUを初めて構築しました。 Dom0はArch Linuxで、DomUも同様です。最近、少なくとも2つのパーティション(ルート+スワップ)が必要なため、設定にLVMが必要であることがわかりました。
現在の問題は、私のLVM設定が何であるかわからないということです。これまでの私の設定は次のとおりです。
$ sudo xl /etc/xen/ArkOS-dev_PV.cfgの生成
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
私のDomU起動設定ファイル:

答え1
これを解決しました:
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"
その後、DomUをインストールした後:
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"
