../core/vcpu.cc:650 SaveStateTo() panic-error: failed to get MSR(4) index=0x3a errno=2, No such file or directory

我正在试用它, 所以按照你的build进行下去, i440 与 q35 也切换了, 但还是出了问题.

$ ./mvisor -c ../config/1.yaml [0.000] ../core/vcpu.cc:650 SaveStateTo() panic-error: failed to get MSR(4) index=0x3a errno=2, No such file or directory

1.yaml:

name: Default configuration
base: q35.yaml

machine:
  memory: 4G
  vcpu: 2
  # Set vcpu thread priority value [-20, 19]
  # A higher value means a lower priority
  priority: 1
  # Turn on BIOS output and performance measurement
  debug: No
  # Turn on hypervisor to lower CPU usage (Hyper-V is used for Windows)
  hypervisor: Yes

objects:
  - name: cmos
    # gmtime for linux, localtime for windows
    rtc: localtime

  - class: qxl
  - class: spice-agent
  - class: qemu-guest-agent
  - class: usb-tablet

  - class: virtio-network
    backend: uip
    mac: 00:50:00:11:22:33

  # - class: virtio-vgpu
  #   memory: 1G
  #   staging: No
  #   blob: No

只是改了vcpu为2, ata-cdrom, ata-disk, hypervisor, 其它配制什么都没改变.

请问host用的是什么系统？

spobit commented 8 months ago

host: OS Name: Microsoft Windows 11 Pro OS Version: 10.0.22631 N/A Build 22631

vmware guest: centos8.5.2111 Linux 192.168.33.138 4.18.0-348.7.1.el8_5.x86_64 #1 SMP Wed Dec 22 13:25:12 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

我有点没看明白，你是在vmware内运行mvisor么？用来运行mvisor的linux系统4.18.0-348.7.1.el8_5.x86_64版本有些低了，建议升级内核到4.18.0-408.el8.x86_64或者更高版本。注意，在vmware内运行要确保打开虚拟机嵌套，这样mvisor才能正确使用到硬件加速

spobit commented 8 months ago

是的, 在vmware里运行. 我这里面有kvm, 应该是打开了.

os的选择是指导里给的,我可以用其它系统,还是升级centos8的内核?

nooodles2023 commented 8 months ago

vmware里再运行mvisor算是嵌套了一层虚拟化效率会有些低，如果有条件的话建议再装有linux系统的主机上运行。确保内核更新到这个版本，或者更新的也可以，目前我们使用最多的也是centos+408这个版本的内核

ok. 我只是纯粹的感兴趣,性能不用考虑.

我可以用 centos stream 吗?

可以的

怎么选择都错, 是要参加硬盘? 有没有详细的安装文档.
