無法在 KVM 中啟動虛擬機/域：無法獲得“寫入”鎖定
主機重啟後，我無法啟動虛擬機：
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]?文件未使用：
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:~$我在 Ubuntu 18.04/qemu 2.11 上試過併升級到 Ubuntu 20.04/qemu 4.2.1
此升級無助於解決問題。
這個虛擬機非常大，因此無法輕鬆地從中創建新虛擬機，沒有可用空間。
有什麼幫助可以從這種情況中恢復並啟動這個域嗎？
謝謝

在這種情況下，這是暫時的鎖衝突，或者在某些情況下我們不應該直接理解這個錯誤。
所以問題在
lslocks輸出中不可見。解決方案是通過以下方式刪除 2 個磁碟副本
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>它不能多次呼叫同一個文件！
希望對某人有所幫助
我想，我很久以前在嘗試
virsh attach-disk docker-1 --target vdx --source /apphd/prod/kvm/storage/docker-1-volume-hd.qcow2 --persistent --driver qemu --subdriver qcow2 --targetbus virtio連接儲存時就離開了
