help please - running a guest from an iSCSI disk ? getting more diagnostics than "cannot make domain: -3" ? how to make domain0 "privileged" ?
...&hypercall)) < 0 )
Value returned is $4 = -1
(gdb) p errno
$5 = 1
Any ideas how to get this working, or on where I could get better
diagnostics ?
I''m guessing this is caused by this code in arch/x86/platform_hypercall.c :
ret_t do_platform_op(XEN_GUEST_HANDLE(xen_platform_op_t) u_xenpf_op)
{
ret_t ret = 0;
struct xen_platform_op curop, *op = &curop;
if ( !IS_PRIV(current->domain) )
return -EPERM;
So how do I make the IS_PRIV macro return non-zero for my domain_0 ,
ie. set d->is_privileged /
make my domain0 into a "privileged" domain ? What i...

[PATCH][cpufreq] Xen support for the ondemand governor [1/2] (hypervisor code)
Modify the cpufreq ondemand governor so that it can get idle and
total ticks from the Xen hypervisor. Linux and Xen have different
ideas of what an idle tick is, so the Xen values for both have to
be returned in the same platform hypercall.

[PATCH v3 0/6] ARM hypercall ABI: 64 bit ready
Hi all,
this patch series makes the necessary changes to make sure that the
current ARM hypercall ABI can be used as-is on 64 bit ARM platforms:
- it defines xen_ulong_t as uint64_t on ARM;
- it introduces a new macro to handle guest pointers, called
XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to
have size 8 bytes on aarch64);
- it replaces all the occurrences of
