RE: [Xen-devel] using 3.1.1 with 256GB host, 11_create_concurrent_pos of xm-test fails with Cannotallocate memory

["Krysan, Susan" <KRYSANS@xxxxxxxxxx>]

Thanks for your response.  This is the first time xen has actually been
allotted 256GB.  I've booted unstable with 256GB before, but xen is only
allotted 166gb (truncated for 32on64 support).  Next week I will run
with a debug build and provide you with the memory stats.

Thanks,

That's interesting. Is this a regression, or the first time you've tried
256GB?

Please can you use a debug build of xen then try sending it 'debug key'
events so we can see the memory stats. You can do this from the serial
console, or inject the key presses via xm.
