物理機重新啟動後無法 virsh 啟動我的 VM。錯誤僅支持單個 IDE 控制器?
我有一個在 kvm 下執行的虛擬機(它是一個 .img 文件),它執行的伺服器嚴重崩潰並重新啟動,最後終於搞定了……我想我跑了
yum install -y qemu-kvm
我確信在一個非常古老的未更新作業系統上更新了很多東西。這台機器死後我遇到了問題,因為它看到 vm 像 KVM 本身一樣在那裡(圖像文件在那裡,但它們沒有在任何地方“註冊”)。不知道我是怎麼把它找回來的,但是所有的 VMS 都啟動了 virsh 但是一個……它給出了一個錯誤:
[root@sdss4-server1 ~]# virsh start sdss-host2 setlocale: No such file or directory error: Failed to start domain sdss-host2 error: unsupported configuration: Only a single IDE controller is supported for this machine type
我的文件損壞了嗎?我可以修理它嗎?我很樂意讓這個虛擬機再次執行,因為沒有備份,並且一些數據需要從它中取出。(我以為我可以以某種方式在 linux 中掛載 .img 文件?但我嘗試了以下方法)
kpartx -av sdsshost2.img add map loop0p1 (253:2): 0 208782 linear /dev/loop0 63 add map loop0p2 (253:3): 0 10490445 linear /dev/loop0 208845 device-mapper: resume ioctl on loop0p3 failed: Invalid argument create/reload failed on loop0p3 add map loop0p3 (0:0): 0 62916711 linear /dev/loop0 10699290 [root@sdss4-server1 vm-cache]# sudo mount /dev/mapper/loop0p2 /mnt/host2 mount: unknown filesystem type 'swap' [root@sdss4-server1 vm-cache]# sudo mount /dev/mapper/loop0p1 /mnt/host2 (I think this is a boot and the files in it are:) System.map initrd-2.4.21-27.0.2.EL.img vmlinux-2.4.21-27.0.2.ELsmp System.map-2.4.21-27.0.2.EL initrd-2.4.21-27.0.2.ELsmp.img vmlinux-2.4.21-32.0.1.EL System.map-2.4.21-27.0.2.ELsmp initrd-2.4.21-32.0.1.EL.img vmlinux-2.4.21-32.0.1.ELsmp System.map-2.4.21-32.0.1.EL initrd-2.4.21-32.0.1.ELsmp.3w-9xxx.img vmlinuz-2.4.21-27.0.2.EL System.map-2.4.21-32.0.1.ELsmp initrd-2.4.21-32.0.1.ELsmp.img vmlinuz-2.4.21-27.0.2.ELsmp config-2.4.21-27.0.2.EL initrd-2.4.21-52.ELBOOT.img vmlinuz-2.4.21-32.0.1.EL config-2.4.21-27.0.2.ELsmp kernel.h vmlinuz-2.4.21-32.0.1.ELsmp config-2.4.21-32.0.1.EL message vmlinuz-2.4.21-52.ELBOOT config-2.4.21-32.0.1.ELsmp message.ja grub vmlinux-2.4.21-27.0.2.EL
當然不是我想要的,看起來 loop0p3 是我想要安裝的,但是 kpartx 給出了一個我不完全理解的錯誤。
那麼我的虛擬驅動器/磁碟壞了嗎?我能做些什麼來恢復這個如何?

有趣的。您確實定義了兩個 IDE 控制器,但兩個虛擬驅動器都使用第一個。您應該能夠安全地移除第二個 IDE 控制器。
具體來說,這個節點應該被刪除:
<controller type='ide' index='1'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </controller>
