[[6.10.0RC2] VM doesn't start because has no space for logs (but does have).]

I'm having the same issue. Here are my diagnostics. 

 

And running the command du -h -d 1 /var/log  initially showed this after rebooting:

0       /var/log/pwfail
4.0K    /var/log/swtpm
20K     /var/log/samba
0       /var/log/plugins
0       /var/log/pkgtools
0       /var/log/nginx
0       /var/log/nfsd
12K     /var/log/libvirt
328K    /var/log

 

 

BUT it showed this just after shutting down a VM I couldn't get to pass through again and had been showing 84 degrees C! (I've been having problems trying to pass through VM's on my new motherboard/setup, though I also added a cache drive and may have messed things up when trying to move around info and to separate VM info onto the new drive.

and after doing the command line that you requested earlier now shows (after shutting down the VM but not rebooting yet)

0       /var/log/pwfail
0       /var/log/swtpm
20K     /var/log/samba
0       /var/log/plugins
0       /var/log/pkgtools
0       /var/log/nginx
0       /var/log/nfsd
7.6M    /var/log/libvirt
128M    /var/log
