Your xen_cmdline is slightly wrong, it should be:

xen_cmdline="dom0_mem=4048M dom0_max_vcpus=4 dom0=pvh com1=9600,8n1 guest_loglvl=all loglvl=all"

Note it's dom0=pvh, not pvh1. And the speed of the serial console
needs to be adjusted to match the one you are using (9600), or you
won't see any output.

Also make sure the line is not split by your editor, or else it won't
be parsed correctly.

Regards, Roger.
