Serial port passthrough and Proxmox console

[m3a2r1]

I've set up serial port for vm and it works correctly but I can get proxmox console to view my machine (there's "unable to find a serial interface" error on start proxmox console). It's Windows 10 so I get it by remote desktop.
Is it possible to using serial port passthrough and proxmox console?

Hi,

Is it possible to using serial port passthrough and proxmox console?

Yes, this works, but how did you configure it?

On GUI I can only set 0,1 etc. for serial port so I've set it on shell with command
qm set VM-number-serial /dev/ttyS0

This works here as expected with latest Proxmox VE and Windows 10.
What Proxmox VE version do you use?

 

[m3a2r1]

6.1-8

So I can't connect to win10 vm when I use passthrough serial port?

Here is the config of the VM were console and VNC is working parallel.

agent: 1
bootdisk: scsi0
cores: 4
cpu: EPYC
ide2: none,media=cdrom
machine: q35
memory: 4096

scsi0: WDSN750:vm-305-disk-0,cache=writeback,discard=on,size=60G,ssd=1
scsihw: virtio-scsi-pci

Which setting is most important?
CPU, machine or vga? What's the type 'qxl' in vga?

OK, I've configured spice for vm step by step and now it works. I can use vnc and spice remote viewer.
