Hi, I have recently completed an installation of BLFS 8.3 (systemd) in an HVM
and am attempting to install Qubes tools on it, ultimately with the idea of
making it PVH.
As far as BLFS is concerned, the installation seems to have gone without issue,
and I have successfully built a kernel that matches the hardware required for
XEN and a working lightdm X11 environment.
Where I'm running into the issue is that qvm-run from dom0 does not seem to
have any effect on the HVM itself. Here are the basic tests for functionality
I have confirmed:
SERVICES RUNNING:
qubes-db.service loaded active running
qubes-early-vm-config.service loaded active exited
qubes-gui-agent.service loaded active running
qubes-meminfo-writer.service loaded active running
qubes-mount-dirs.service loaded active exited
qubes-qrexec-agent.service loaded active running
qubes-sysinit.service loaded active exited
meminfo-writer is checked in the gui
MOUNTS:
xen on /proc/xen type xenfs (rw,relatime)
/dev/xvdb on /rw type ext4 (rw,relatime,discard)
/dev/xvdb on /home type ext4 (rw,relatime,discard)
/dev/xvdb on /usr/local type ext4 (rw,relatime,discard)
#/dev/xvdc I somehow messed up, but I'm guessing isn't relevant to qvm-run
MODULES:
# lsmod
Module Size Used by
tmem 16384 -2
u2mfn 16384 -2
All the other modules, e.g., evtchn are built-in; this is a compact kernel with
what I felt were the very bare minimum, but ultimately will be replaced with
the PVH kernel. I attempted to use qubes-linux-kernel, but had issues with the
dependency on rpms.
TESTS FOR OPERABILITY:

`ls -la /tmp` shows no sign of '/tmp/dummy', same as with `sudo touch
/tmp/dummy`
Are there other logs I can provide to give a clearer picture of my install?
Are there any more-verbose way I can check why qrexec isn't working as expected?
