主机重启后，我无法启动虚拟机：
user@server-1:~$ virsh start docker-1
error: Failed to start domain docker-1
error: internal error: process exited while connecting to monitor: 2021-03-23T01:21:58.149079Z qemu-system-x86_64: -blockdev {"node-name":"libvirt-2-format","read-only":false,"driver":"qcow2","file":"libvirt-2-storage","backing":null}: Failed to get "write" lock
Is another process using the image [/apphd/prod/kvm/storage/docker-1-volume-hd.qcow2]?
文件未在使用中：
user@server-1:~$ sudo fuser -u /apphd/prod/kvm/storage/docker-1-volume-hd.qcow2
user@server-1:~$ sudo lsof | grep qcow
user@server-1:~$ virsh list
Id Name State
--------------------
user@server-1:~$
我已在 Ubuntu 18.04/qemu 2.11 上尝试过，并升级到 Ubuntu 20.04/qemu 4.2.1
这次升级并没有帮助解决问题。
这个虚拟机非常大，因此无法轻松地从中创建新的虚拟机，因为没有可用空间。
有什么帮助可以帮助从这种情况中恢复并启动这个域吗？
谢谢

答案1
在这种情况下，这是瞬时的锁冲突，或者在某些情况下我们不应该直接理解这个错误。
lslocks因此问题在输出中不可见。
解决方案是通过以下方式删除 2 个磁盘重复项virsh edit docker-1：
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/apphd/prod/kvm/storage/docker-1-volume-hd.qcow2'/>
<target dev='vdb' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
</disk>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/apphd/prod/kvm/storage/docker-1-volume-hd.qcow2'/>
<target dev='vdc' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</disk>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/apphd/prod/kvm/storage/docker-1-volume-hd.qcow2'/>
<target dev='vdx' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
</disk>
它不能多次调用同一个文件！
希望对某人有帮助
virsh attach-disk docker-1 --target vdx --source /apphd/prod/kvm/storage/docker-1-volume-hd.qcow2 --persistent --driver qemu --subdriver qcow2 --targetbus virtio我想，我在尝试连接存储时已经离开了这个
