使用KVM进行实时迁移
我想要在两台主机之间实时迁移虚拟机，为此我使用以下命令：
virsh migrate vmtest qemu+ssh://[email protected]/system
我收到以下错误消息：
error: internal error process exited while connecting to monitor: char device redirected to /dev/pts/3
qemu: could not open disk image /vms/vmtest.qcow2: No such file or directory
/vms/vmtest.qcow2 是我要迁移的虚拟机的硬盘映像 两台主机的配置从机器架构到 qemu 版本完全相同。我没有扰乱任何主机上的任何 iptables 设置。默认网络在两台主机上均处于活动状态。命令中是否有任何问题，或者此错误消息是否意味着什么（对我来说不是）。
I want live migration of virtual machines between two host and for that i am using following command:
virsh migrate vmtest qemu+ssh://[email protected]/system
I am getting the following error message:
error: internal error process exited while connecting to monitor: char device redirected to /dev/pts/3
qemu: could not open disk image /vms/vmtest.qcow2: No such file or directory
/vms/vmtest.qcow2 is the harddisk image of the virtual machine i want to migrate
The configuration of both the hosts is exactly same form machine architecture to qemu version. I haven't disturbed any iptables settings on any of the hosts. Default network is active on both the hosts. Is there any thing wrong in the command or if this error messages means something (not to me).

创建一个 nfs 池或任何其他类型的共享主机并尝试进行迁移。
Create a nfs pool or any other kind of shared hostage and try doing the migration.
