This patch implements full support for memory ballooning in the QEMU driver.
- Fix qemudBuildCommandLine() to set the initial boot time VM memory allocation based off the 'maxmem' config field. - Add call to 'qemudDomainSetMemoryBalloon' immediately at startup to make the guest balloon to initial requested allocation. - In the qemudDomainGetInfo() and qemudDomainDumpXML calls, query the monitor to find current balloon allocation and update config - Implement qemudDomainSetMemory() for running guests using the monitor balloon command
In all of these scenarios, if the QEMU being used is too old to support the memory balloon device, the user will get a suitable error or it'll report the statically defined memory allocation from boot time.
Updated, with the bugs Cole noticed fixed.
Patch looks fine to me, maybe this should be applied now, thanks ! Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
