Adding "dom0_mem=512" to the "Boot Options" line of GRUB (so that it gets
appended to the "kernel /xen.gz" line) causes boot failure. The machine briefly
displays a message with lots of asterisks and a text along the lines of:
"Panic: Dom0 allocation too small for kernel image, rebooting"
and then reboots. I found no way of keeping the message on screen long enough
to copy the full text.
Adding "dom0_mem=512" to the "More Options" line of GRUB (which ends up on the
"module /vmlinuz" line, ie. on the Linux kernel parameters) does not have any
noticeable effect.
Adding "swiotlb=96" to the "More Options" line seems to fix the problem, ie. no
"Out of SW-IOMMU space" messages appear in /var/log/messages.
