Subject: [PATCH] fix xen hvm direct kernel boot
|
|
|
|
Since commit a1666142: acpi-build: make ROMs RAM blocks resizeable,
|
|
xen HVM direct kernel boot failed. Xen HVM direct kernel boot will
|
|
insert a linuxboot.bin or multiboot.bin to /genroms, before this
|
|
commit, in acpi_setup, for rom linuxboot.bin/multiboot.bin, it
|
|
only needs 0x20000 size; after the commit, it will reserve x16
|
|
size for resize, that is 0x200000 size. It causes xen_ram_alloc
|
|
failed due to running out of memory.
|
|
|
|
To resolve it, either:
|
|
1. keep using original rom size instead of max size, don't reserve x16 size.
|
|
2. guest maxmem needs to be increased. (commit c1d322e6 "xen-hvm: increase
|
|
maxmem before calling xc_domain_populate_physmap" solved the problem for
|
|
a time, by accident. But then it is reverted in commit ffffbb369 due to
|
|
other problem.)
|
|
|
|
For 2, more discussion is needed about howto. So this patch tries 1, to
|
|
use unresizable rom size in xen case in rom_set_mr.
