Hi, Thanks for your reply:-)
Now, I know that the windows VM is crashed due to a not fully booted stub
domain. But why did the stub domain crash?
Thanks:-)

Hi, everyone.
I'm trying to run a Windows HVM vm with stub domain in xenserver-6.5, whose
internal xen version is xen-4.4-xs88306. After I started the vm, both the
vm and its corresponding stub domain crashed. Here is the related content
in hypervisor.log. The domain ID of the windows vm is 1, and

Sorry for replying so late. Libvmi is used to substract information of
guest, such as system calls. But I don't think it can be used to intercept
hypercalls as hypercall is a behavior between guest and hypervisor while
syscall is a behavior between guest applications and guest kernel. Anyway,

Add is_pvh_32bit_domain() macro and use it alongside is_pv_32bit_domain() where
necessary.
Since PVH guests cannot change execution mode, has_32bit_shinfo is a good
indicator of whether the guest is PVH and 32-bit.

The armhf tests in distros-debian-* have always failed since they did not

The remainder of the series consists of various fixes, extensions to

This is under the same conditional as the nobootloader confirmation

always_halt results in d-i calling "halt", which does not necessarily
poweroff the host (it seems to for x86/PV Xen guests, but does not for
ARM). Using exit/poweroff calls "poweroff" which is equivalent to
"halt -p", doing so results in ARM guests powering off as desired.

The current gunzip code to decompress the Dom0 kernel is implemented in
inflate.c which is included by bzimage.c.
I am looking to doing the same on ARM64 but there is quite a bit of
boilerplate definitions that I would need to import in order for
inflate.c to work correctly.
Instead of copying/pa
Free the memory used for the compressed kernel and update the relative
mod->start and mod->size parameters with the uncompressed ones.

Hi all,
this patch series introduces support for gzipped kernels, such as the
standard Image.gz format used by Linux on arm64 by default, in Xen on
arm. Without it, Xen cannot load the default kernel shipped by distros,
such as CentOS 7.

A 32-bit entry point to a DMI table says how many structures the table
contains. The SMBIOS specification explicitly says that end-of-table
markers should be ignored if they are not actually at the end of the
DMI table. So only honor the end-of-table marker for tables accessed

The function shouldn't return NULL after having obtained a reference,
or else the caller won't know to drop it.
Also its result shouldn't be ignored - if calling code is certain that
a page already has a non-zero refcount, it better ASSERT()s so.
Finally this as well as get_page() and put_page()
