Been using for about a month now, no recalled issues regarding install.
* Win10 Qubes Windows Tools no success.
* Using qubes-mirage-firewall to completely replace sys-firewall's default. mirage doesn't work with HVMs, but works with [mirage] -> [intermediary (happens to be work VPN via openvpn-cli)] -> win10
* audio and video work out of the box, but playonlinux seems to be really choppy on some starts and a restart gets it back to usable performance
* dom0 sometimes uses up 60% of 8 vcpus, but no apparent (or at least user-invoked) processes or work
* fedora-28-minimal installed after-the-fact, but absence of iptables packages made it problematic to originally replace firewall (this is what led me to mirage). Otherwise, documentation for turning fedora-28-minimal into useful domain very good.
* ReactOS v.48 installer could not detect HDD to install to via HVM attempt
* It's confusing that dom0 only reports 4gb (of 16) in TOP, seeing as how I have never set 4gb in any configuration (164/288 min/boost values). 16GB is recognized in xentop, however.
* fedora-28-dvm always has 'updates pending!' icon in qubes manager, even when no other domains/templates have the icon listed.
