It tells you if domains _d has special privileges over the domain _t
(the target). This is typically true of domains which are privileged Âin
general (the IS_PRIV check, typically true only for dom0) or of stub
domains for HVM which have their ->target set via XEN_DOMCTL_set_target.

However this is all a red-herring since you are seeing ESRCH and not
EPERM as described in my other mail.

Ian.

What do you mean by that `
However this is all a red-herring since you are seeing ESRCH and not
EPERM as described in my other mail.Â` The src/xen/include/xen/errno.h Âdefines:

 4#define EPERM    Â1 Â/* Operation not permitted */

 5#define ENOENT    2 Â/* No such file or directory */

 6#define ESRCH    Â3 Â/* No such process */

Besides, the xc error logging reported -1 and 3, you said -1 only told there was an error occurring and 3 is the real reason?!

Maybe I misunderstood your real meaning.
