Re: [Xen-devel] Is this a bug of xentrace?

[Hui Kang <hkang@xxxxxxxxxxxxx>]

Yes, it is 0x00007fff. This is one line  in the parsed trace file.
CPU1  962569711226060 (+     574)  switch_infnext    [ new_domid = 
0x00007fff, time = 14321, r_time =30000000 ]
When I use "xm list", it shows the domain id is 5. There are only two 
domains on the host.
Can any one point out what does "0x00007fff" this number mean? Thanks.
