And though the libvirtd status was good, virt-manager couldn't connect and nothing would run. I noticed an odd APIC warning in dmesg about conflicting address space surrounding some nvidia stuff though, and wondered if that had anything to do with it. So I uninstalled rc6 and the Tk-Glitch nvidia-dkms drivers I had to use for rc6, and reinstalled the normal nvidia-dkms drivers. But the dmesg warning is still present with my working 5.5.4 kernel, and my VM runs great, so I don't think that has anything to do with it. Nevertheless I'm attaching the full dmesg output I got at boot. I'll be up for another few hours so if you need anymore help today I'll get right on it. My son is getting married tomorrow though so I won't be available, but from Sunday on I'll be back online. Thanks for all your help gentlemen! -- You are receiving this mail because: You are watching the assignee of the bug.
