Stopped start failed: QEMU exited with code 1

[deadbrook]

Good afternoon !

I have a VM that started showing me the error below, could you help me?

kvm: -drive file=/dev/pve/vm-102-disk-0,if=none,id=drive-sata0,format=raw,cache=none,aio=native,detect-zeroes=on: Could not open '/dev/pve/vm-102-disk-0': No such file or directory

TASK ERROR: start failed: QEMU exited with code 1

Could not open '/dev/pve/vm-102-disk-0': No such file or directory

The virtual disk cannot be found. Check your storage system why the disk is lost.

Hi I am having a similar issue with Qemu exiting with code 1....here is the message:

kvm: error: failed to set MSR 0xe1 to 0x0
kvm: /build/pve-qemu/pve-qemu-kvm-5.1.0/target/i386/kvm.c:2713: kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.
TASK ERROR: start failed: QEMU exited with code 1

Note: I am running proxmox on top of Vmware Workstation as nested virtualization. We are testing proxmox pve for a LARGE project.

Best regards

Reuben

echo 1 > /sys/module/kvm/parameters/ignore_msrs

if that works, you can make it permanent via the kernel cmdline

 

[Reuven]

thanks fabian. It did it. How do I "make it make it permanent via the kernel cmdline"....any article you can point me too to accomplish it ?

Hi fabian...thanks for your reply and help. I admit it...I am new to linux...I tried to implement what is written in the link above:

"3.11.5. Editing the Kernel Commandline​

You can modify the kernel commandline in the following places, depending on the bootloader used:
Grub
The kernel commandline needs to be placed in the variable GRUB_CMDLINE_LINUX_DEFAULT in the file /etc/default/grub. Running update-grub appends its content to all linux entries in /boot/grub/grub.cfg.
Systemd-boot
The kernel commandline needs to be placed as one line in /etc/kernel/cmdline. To apply your changes, run pve-efiboot-tool refresh, which sets it as the option line for all config files in loader/entries/proxmox-*.conf. "

you gave me: echo 1 > /sys/module/kvm/parameters/ignore_msrs and i ran it in the termi al and it worked...now
in order to make it permanent I did:

1) nano the /etc/default/grub and added this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet /sys/module/kvm/parameters/ignore_msrs"
2) then I ran update-grub

3) then I nano /etc/kernel/cmdline and the file is empty...I am sure i am doing something wrong at this point...

.could you please point me in the right direction....thanks and all the best reuven

 

[fabian]

well, the first thing to check is whether your system boots using grub or using systemd-boot (when in doubt you can add the option in both places/files though).

the actual stanza you want to add to the cmdline is kvm.ignore_msrs=1. the rest works like in the instructions

 

[Reuven]

Hi Fabian thanks for your reply and your hand holding. It is greatly appreciated.

Regarding the boting question my system is using Grub 2.02+dfsg1-18pve1.
Quick question:
are the steps 1 and 2 above ok ? If so, then I should add the stanza to which file or files? /etc/kernel/cmdline?

All the best Reuven

 

[fabian]

no, either to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub (followed by update-grub to refresh the grub config), or to /etc/kernel/cmdline (followed by pve-efiboot-tool refresh to refresh systemd-boot's config - or both if you are not sure which bootloader is used.

 

[Reuven]

Thanks fabian...your the best...it worked like a charm...all the best reuven

Hi there.

I am having the same problem as @Reuven had. However, modifying the file 1) nano the /etc/default/grub and added this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet /sys/module/kvm/parameters/ignore_msrs" . 2) then I ran update-grub . And also modifying/creating the file 1) /etc/kernel/cmdline and added this line: kvm.ignore_msrs=1 . 2) then ran pve-efiboot-tool refresh.
Did not work in any or both solutions and I still get the same error " Stopped start failed: QEMU exited with code 1"

However, running this command echo 1 > /sys/module/kvm/parameters/ignore_msrs, it does work and the VM can be started without any problem.

could any of you tell me how you actually solved this problem permanently, please?

edit: I am using nested virtualization windows 10 (host) -> VMware workstation 16 pro -> latest Proxmox (6.3-2)

 

[fabian]

you need to add 'kvm.ignore_msrs=1' to the GRUB_CMDLINE_LINUX_DEFAULT variable, not the sys path and value..

 

[farofa]

Thanks, it did work now.

did you perform upgrades? have you rebooted afterwards? please do if you havent.
if the reboot doesnt fix the issue post your pveversion -v output and the VM configuration qm config VMID

Hello,

I am new to proxmox.

I have an errors:

Could anyone advise how to fix that?
