Subject: pc: fix qemu exiting with error when -m X < 128 with old machine types
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.2~209^2~691
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5734d031aa2fdb442410ca958ca5382d54fd71ff;p=sdk%2Femulator%2Fqemu.git

pc: fix qemu exiting with error when -m X < 128 with old machine types

If machine doesn't support memory hotplug then starting QEMU
with initial memory less than default will make QEMU exit with
following error message:

$QEMU -m 16  -M isapc
qemu-system-i386: "-memory 'slots|maxmem'" is not supported by: isapc

Set maxram_size to initial memory value before parsing
'maxmem' option allows to keep maxmem in sync with initial
memory size if no maxmem option was specified.
