SPICE input broken in B7-rc1

[bandithedoge]

This happened after updating both the host and client applications to B7-rc1. B6 did not have this issue on the exact same VM. I tried manually specifying the SPICE address and port and that didn't help. I have the virtio-win drivers and SPICE guest tools installed.

(before you ask, yes, that's a Haswell IGPU passed through, it worked perfectly fine in B6)

This is not a bug but a user error. You have another SPICE server listening on localhost:5900 that the LG client is connecting to. It can be another application or maybe another VM. That part of the code hasn't changed for more than 3 years so there's no chance of a regression here.

Also, please note that, as was quoted in the issue opening message you filled, support issues should be reported on LG's primary support channels (the forum and/or the Discord LG channel) and not this GitHub repo issue tracker. The issue tracker should only be used to report bugs in the code itself.

[netboy3]

Also, please note that your VM is badly configured: 00:00:16.803 [I] main.c:1622 | lg_run | CPU : 4 sockets, 4 cores, 4 threads

You do not have 4 single thread 4 core sockets.

And

00:00:16.803 [W]              main.c:1652 | lg_run      | I have detected you have a CPU with hyperthreads but your guest is not aware of this                                                
00:00:16.803 [W]              main.c:1655 | lg_run      | This will result in a degredation of latency sensitive tasks including the use of Looking Glass

Consider visiting the VFIO support channels on the forum and/or Discord to get assistance in configuring your VM properly.

I have no other VM running. The only thing that could interfere with it could be the virt-manager window, although disabling the Autoconnect option to make sure it doesn't grab SPICE input doesn't help. This didn't matter on B6 as opening LG would simply disconnect it and vice versa.

Thank you, I didn't catch that. I thought that simply setting vCPU allocation in the CPUs tab to match Logical host CPUs would copy the host CPU topology.

libvirt reports the guest ID is f669939d-8f52-41f9-9230-df00d73b497d, your VM report's its ID is 00000000-0101-0001-0000-000000000000. This is not a Looking Glass issue, you have done something to prevent windows reporting it's proper ID.

[bandithedoge]

I just downgraded to B6 and everything works fine. Maybe there is a regression after all.

[gnif]

There is no regression, B6 didn't check the guest UUID matched the UUID reported by spice. You need to fix your VM, this is not a bug.
