virt-filesystems工具的使用
主要参考了man page
virt-filesystems
列出在虚机或磁盘镜像里的文件系统、分区、块设备、LVM
virt-filesystems - List filesystems, partitions, block devices, LVM in a virtual machine or disk image
-a：后接磁盘镜像
[root@cloudmanager datapool]# virt-filesystems -a centos56x64
/dev/sda1
/dev/vmvg/root
[root@cloudmanager datapool]# virt-filesystems -a win2003ent32chs
/dev/sda1
[root@cloudmanager datapool]# virt-filesystems -a win2008ent64chs
/dev/sda1
--extra：If you add --extra then non-mountable (swap, unknown) filesystems are shown as well:
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --extra
/dev/sda1
/dev/vmvg/root
/dev/vmvg/swap
-l：输出额外的一些分区信息，包括分区的size，label，vfs，type
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 -l
Name Type VFS Label Size
/dev/sda1 filesystem ext3 /boot 205599744
/dev/vmvg/root filesystem ext3 - 6207569920
-d：后面接的是libvirt的domain，就是虚机名
[root@cloudmanager datapool]# virt-filesystems -d nagios -l
Name Type VFS Label Size
/dev/sda1 filesystem ext3 /boot 205599744
/dev/vmvg/root filesystem ext3 - 102844334080
--partitions：只列出分区，不会列出已经被格式化的文件系统
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --partitions
/dev/sda1
/dev/sda2
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --partitions -l
Name Type MBR Size Parent
/dev/sda1 partition 83 205599744 /dev/sda
/dev/sda2 partition 8e 10528358400 /dev/sda
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --partitions -l --extra
Name Type VFS Label MBR Size Parent
/dev/sda1 filesystem ext3 /boot - 205599744 -
/dev/vmvg/root filesystem ext3 - - 6207569920 -

--logical-volumes:列出LV卷（lvs）
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --logical-volumes
/dev/vmvg/root
/dev/vmvg/swap
--volume-groups:列出VG卷（vgs）
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --volume-groups
/dev/vmvg
--physical-volues:列出PV卷（pvs）
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --physical-volumes
/dev/sda2
--block-devices:列出块设备
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --block-devices
/dev/sda
--filesystems:列出文件系统
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --filesystems
/dev/sda1
/dev/vmvg/root
--all:列出所有，包括块，文件系统，lv等信息
-h：以M或者G显示大小
--uuid：列出设备的uuid
[root@cloudmanager datapool]# virt-filesystems -a centos56x64 --all --long --uuid -h
Name Type VFS Label MBR Size Parent UUID
/dev/sda1 filesystem ext3 /boot - 196M - 0b99a0f7-3de3-45c4-b727-e95e3065c13c

--format：强制更改镜像的格式
[root@cloudmanager datapool]# virt-filesystems --format=raw -a centos56x64
-V：输出版本信息
-v：输出debug信息
-x：输出trace的信息
