Hi, I have a couple of questions regarding reproducing the issue: 1. How do you instantiate virtio serial in QEMU? 2. How do you uninstall the driver? 3. Which of the driver verifier options are enabled? 4. What is memory_leak_check? Where is it enabled/disabled? Thanks, Viktor Also, 5. Does QEMU guest agent installed? 6. Does virtio serial really transfers some data in this case? 1. How do you instantiate virtio serial in QEMU?
A:
-chardev socket,server=on,id=chardev_vs1,wait=off,path=/var/tmp/avocado_n48c8i8m/serial-vs1-20230726-234057-ZVZ3OV0h \
-device '{"id": "virtio_serial_pci0", "driver": "virtio-serial-pci", "bus": "pci.0", "addr": "0x3"}' \
-device '{"id": "vs1", "driver": "virtserialport", "name": "vs1", "chardev": "chardev_vs1", "bus": "virtio_serial_pci0.0", "nr": 1}' \
2. How do you uninstall the driver?
It's not actually uninstalling the driver. just disabled driver.
3. Which of the driver verifier options are enabled?
`verifier /standard /driver` vioser.sys`
4. What is memory_leak_check? Where is it enabled/disabled?
the memory_leak_check just disable/enable the driver and after that, checks whether there is BSOD situation. that's the whole 'memory_leak_check'
5. Does QEMU guest agent installed?
not at all,
6. Does virtio serial really transfers some data in this case?
exactly, it does have it.
Could you please explain what kind of communication goes through this virtio serial port? Also, what is the Windows version? (In reply to Viktor Prutyanov from comment #15) > Also, what is the Windows version? win10/win2019_x86_64 (In reply to Viktor Prutyanov from comment #14) > Could you please explain what kind of communication goes through this virtio > serial port? I'm not sure I understand your question quite clearly, it's data transmission. Create a data block inside VM and then run.py script to send&recieve data from host to guest(or guest to host).

Thanks, Yan. Issue migration from Bugzilla to Jira is in process at this time. This will be the last message in Jira copied from the Bugzilla bug. |
