Re: [Xen-devel] Unable to create guest PV domain on OMAP5432

[Jayadev Kumaran <jayadevk123@xxxxxxxxx>]

Hello Konrad,

Apologies for the incomplete mail. Adding to the previous reply;

>> not allocate order=18 extent: id=4 memflags=0xc0 (0 of 1)libxl: error:

> looks like it could not allocate memory?

In my configuration file, i had used "memory=1024" . However if I use any value <=512 , the above error log is not seen. However the rest of the logs appear and it is still unable to add disk devices.

Regards
