I have installed PVE 6.2, and started a ubuntu 18.04 vm. The ubuntu installed with asterisk and 3g dongle drivers and attached 5 usb dongles.
But the systems will halt without any warning and the console will lost.
Even reset cannot be done.
TASK ERROR: VM 305 qmp command 'system_reset' failed - unable to connect to VM 305 qmp socket - timeout after 31 retries

Force off is required to restart the vm and it will halt sometimes again.
Sometimes it lasts for hours, but sometimes it stopped in 10 minutes.

In which log I should examine the potential issue? Thanks.

Is there something in /var/log/syslog or dmesg for that time?

thanks for your reply. Now my vm died again, and I will check the syslog dmesg (in VM) for anything meaningful. For this time, the vm alive for about 4 hours.

Died at around Aug 29 04:25:17 - 18

For now the /var/log/syslog in host shows some activities on usb when the vm died.
