Hi, all
I have the same problem.
The following is additional infomation.

reboot.

I tried to test it.
The result is :
1.rm /var/lib/xenstored/tdb
2.setting dom0_mem=262144, and reboot
3.At this time, "xm list" show Dom0 is 256MB.
4.setting dom0_mem=524288, and dom0 is rebooted.
5.BUT "xm list" remain in 256MB.
1.rm /var/lib/xenstored/tdb
2.setting dom0_mem=262144, and reboot
3.At this time, "xm list" show Dom0 is 256MB.
4.rm /var/lib/xenstored/tdb
5.setting dom0_mem=524288, and dom0 is rebooted.
6.YES "xm list" show Dom0 is 512MB.
I think tdb should be re-create every time dom0 is started.
Am I correct?
Sincerely Yours,
Nakato
