Hi Daniel, thanks for reply. Well, it seems that I'm a bit ahead of time here, the balloning support didn't even make it to QEMU trunk... So there is not big hurry with it :) To answer Your questions: > can you detect its presence at runtime ? from a slight look to patches yes, it will be possible using monitor "info ballon" command which will print either "Ballooning not activated in VM" or "balloon: actual=%d", so I guess this should be sufficient. > I doubt anybody would object code adding the feature, the problem > is getting the code and something that fail/work reliably depending > on the vailability of the driver. Seems like this should not be that complex. I'll give ballooning patches a try and if it works well, I'll try to prepare some libvirt patches. I'll let You know about progress OK? > Daniel regards nik -- ------------------------------------- Nikola CIPRICH LinuxBox.cz, s.r.o. 28. rijna 168, 709 01 Ostrava tel.: +420 596 603 142 fax: +420 596 621 273 mobil: +420 777 093 799 www.linuxbox.cz mobil servis: +420 737 238 656 email servis: servis@xxxxxxxxxxx ------------------------------------- -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
