Re: ballooning. I don't _think_ so, but not sure how to verify that.

Currently, my DomO's cmd line is

	xen_commandline        : dom0_mem=4096M,max:4096M dom0_max_vcpus=1 
dom0_vcpus_pin=true cpuidle=1 cpufreq=xen clocksource=hpet iommu=verbose 
sched=credit vga=gfx-1920x1080x16 com1=115200,8n1,pci console=com1,vga 
console_timestamps sync_console console_to_ring conring_size=64 
earlyprintk=vga,keep log_buf_len=16M sched_debug apic_verbosity=verbose 
debug loglvl=debug guest_loglvl=debug
Yes, I'm sure it's subject to improvement.

On the guest,

	Kernel command line: BOOT_IMAGE=/vmlinuz root=LABEL=ROOT 
resume=LABEL=SWAP kbdtype=us headless text quiet nofb apparmor=0 edd=off 
splash=silent noshell showopts net.ifnames=0 console=ttyS0,19200n8 
systemd.log_level=info systemd.log_target=kmsg

Haven't yet checked.

Atm, I've only UEFI guests, setup.  To test, I'll just have to spin up a 
non-UEFI guest.  A bit later ...
