Does it come up with the purple waiting screen?

The_Poot · March 31, 2019, 12:28am

trexd · March 31, 2019, 12:30am

What does the terminal say at that time?

The_Poot · March 31, 2019, 12:32am

trexd · March 31, 2019, 12:34am

Do you have display spice and spice channel like in mine?

The_Poot · March 31, 2019, 12:35am

do i need both?

trexd · March 31, 2019, 12:35am

I would try it and see.

The_Poot · March 31, 2019, 12:40am

can you show me what is inside of display spice and inside channel spice

trexd · March 31, 2019, 12:44am

All I did was go ‘Add Hardware’ -> ‘Channel’ and then set things to spice. Also ‘Add Hardware’ -> ‘Graphics’ -> ‘Type’ and set it to spice as well.

The_Poot · March 31, 2019, 12:46am

spice port or spice agent inside of channel

trexd · March 31, 2019, 12:46am

Agent

I currently am running Windows 10 with GVT-g. Because libvirt is having issue with properly resizing the display, I thought it would be a good opportunity to try out Looking Glass.

However, I am running into an issue when trying to compile the client for Linux:

$ make

I did a dnf provides *spice/error_codes.h to see what package I was missing; however, I already have the spice-protocol package installed (unless I was also suppose to install the mingw packages):

$ sudo dnf install spice-protocol

Package spice-protocol-0.12.15-1.fc29.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!

I use this command to get all of the dependencies:

Does anyone know what I am doing wrong here?

You’re doing nothing wrong, RedHat removed that header. Unfortunately you have no choice but to move to the latest version in git where this has been fixed, or wait until the next release.

Hello.
I’m on Arch, kernel 5.05, latest everything.

I have gotten everything set up with a Windows 10 VM, GPU passed through (RX 590), drivers installed, and so on. I have keyboard and mouse set up with evdev, where you mash both control keys to switch.

I then got Looking Glass set up.

It is working at first, but then after about 2-5 minutes it just freezes. The cursor in Windows shows it busy, as if it is accessing storage, and it just freezes. I think Looking Glass is freezing, as when I look into the Virtual Machine Manager app, it shows processor activity continuing and varying for the VM.

I ran
journalctl
to see what came up but nothing looked wrong to me.

What are my next steps?
Thanks
