With the addition on PVH code to xen 4.4, domain.is_hvm no longer
exists. This prevents crash from using a xen 4.4.0 vmcore.
Patch 1 "fixes" this.
Patch 2 is a minor fix in that outputing the offset in hex for
domain_domain_flags is different.
Patch 3 is a bug fix to get all "domain_flags" set, not just the 1st
one found.
Patch 4 is a quick way to add domain.guest_type support.
Don Slutz (4):
Make domian.is_hvm optional
xen: Fix offset output to be decimal.
xen: set all domain_flags, not just the 1st.
Add basic domain.guest_type support.

Hi Don,
The patch looks good to me. But for the crash.changelog, can you show
what happens when you attempt to look at one of these PVH dumps without
your patches?
Thanks,
Dave

With the addition on PVH code to xen 4.4, domain.is_hvm no longer
exists. This prevents crash from using a xen 4.4.0 vmcore.
Patch 1 "fixes" this.
Patch 2 is a minor fix in that outputing the offset in hex for
domain_domain_flags is different.
Patch 3 is a bug fix to get all "domain_flags" set, not just the 1st
one found.
Patch 4 is a quick way to add domain.guest_type support.
Sorry for late reply but I was on holiday.
Nice work. Thanks. I have done some tests with old
and new Xen versions and it looks that it works
without any issue.
