CPU爆满、虚拟机死机问题

Featured Replies

环境:

1、unraid版本6.12.2,阵列中的一个共享文件夹(media)使用VirtIO-Fs共享模式共享给虚拟机(Windows10),虚拟机中安装winfsp并启动服务,获得盘符“Z”

2、docker中安装qbittorrent(下载目录为media)。

3、media未通过cache缓存。

症状:

1、上传和下载大约4-5小时左右会出现CPU全红,虚拟机也死机的状态。

2、qbittorrent工作下CPU未全红和死机的时候CPU负载很高。

排查:

1、停止docker中的qbittorrent,在虚拟机(Windows10)中安装和继续使用qbittorrent问题依旧。

2、直通物理网口给虚拟机使用问题依旧。

3、进入虚拟机(Windows10)手动停止VirtIO-Fs Service服务,目前好的,负载正常。

措施(临时):

进入虚拟机(Windows10)手动停止VirtIO-Fs Service服务;docker安装webdav然后虚拟机(Windows10)安装clouddrive挂载到本地并指定盘符“Z”,算是得到临时解决。

但使用VirtIO-Fs共享模式给虚拟机后死机问题我是解决不了了,请各位大佬指导。

昨天结论下早了

跑了一夜,问题依旧。

remove memfd and shared, VirtioFS is not 100% stable due to memoryBacking looking to update QEMU in the next Version which may fix this issue.

我也是这个问题,请问解决了吗

edge浏览器有没有开“硬件加速”?

windows的安全中心,把内核隔离这些,都关掉,试试?

这是qemu的问题,最新版unraid的qemu版本(7.2)已经解决了这个问题
