Public bug reported:
virt-manager 1:1.3.2-0ubuntu2
For some reason virt-manager (or libvirt) is trying to change the *ownership*
of the ISO file I'm using to install ubuntu. That ISO file is perfectly
readable by the libvirt-qemu user:
$ sudo -u libvirt-qemu -H ls -lah
/mybook/downloads/isos/ubuntu/16.04/ubuntu-16.04-beta2-desktop-amd64.iso

$ sudo -u libvirt-qemu -H file
/mybook/downloads/isos/ubuntu/16.04/ubuntu-16.04-beta2-desktop-amd64.iso
/mybook/downloads/isos/ubuntu/16.04/ubuntu-16.04-beta2-desktop-amd64.iso:
DOS/MBR boot sector ISO 9660 CD-ROM filesystem data (DOS/MBR boot sector)
'Ubuntu 16.04 LTS amd64' (bootable); partition 2 : ID=0xef, start-CHS
(0x3ff,254,63), end-CHS (0x3ff,254,63), startsector 3071200, 4736 sectors
That file is in a remote CIFS share, mounted at mybook:
$ mount|grep mybook
//mybook/Public on /mybook type cifs
(rw,relatime,vers=1.0,cache=strict,username=andreas,domain=MYBOOK,uid=1000,forceuid,gid=0,noforcegid,addr=10.0.10.176,unix,posixpaths,serverino,mapposix,acl,rsize=61440,wsize=65536,actimeo=1,user=andreas)
virt-manager crashes like this:
Error starting domain: unable to set user and group to '125:138' on
'/mybook/downloads/isos/ubuntu/16.04/ubuntu-16.04-beta2-desktop-amd64.iso':

libvirtError: unable to set user and group to '125:138' on
'/mybook/downloads/isos/ubuntu/16.04/ubuntu-16.04-beta2-desktop-amd64.iso':

The workaround is to copy the ISO file from my NAS to my laptop, perform
the install, then delete said ISO file.
