[PATCH 0 of 2] xenpaging:speed up page-in
The following two patches are about how to speed up in xenpaging when page in pages.
On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds,
but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause
unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash.
What鈥檚 more,the dom0 is always in high I/O pressure.

event channel in xenpaging
Hi,Olaf,
I have some questions about event channel in Xenpaging to ask you.
1) In xenpaging it uses Inter-Domainain Commnication (IDC) between
dom0 and domU to build bidirectional connection,but I found there is
only an event channel notification from xen to dom0 when page faults
happens.It seems that xenpaging_resume_page()->xc_evtchn_notify()
doesn''t make any difference.So why

Some problems about xenpaging
Hi, Olaf
we have tested the xenpaging feature and found some problems.
(1) the test case like this : when we start a VM with POD enable, the xenpaging is started at the same time.
this case will cause many problems ,finally, we fixed the BUG, the patch is attached below.
(2) there is a very serious problem. we have observed many VM crash examples, the error code is not always the same.

[PATCH v3 0/4] Nested VMX: APIC-v related bug fixing
From: Yang Zhang <yang.z.zhang@Intel.com>
The following patches fix the issue that fail to boot L2 guest on APIC-v
available machine. The main problem is that with APIC-v, virtual interrupt inject
L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running,
L1 will detect interrupt through vmexit with reason external interrupt. If this happens,
we should update

[PATCH 0 of 2] v2: memshare/xenpaging/xen-access fixes for xen-unstable
The following two patches allow the parallel use of memsharing, xenpaging and
xen-access by using an independent ring buffer for each feature.
Please review.
v2:
- update mem_event_check_ring arguments, check domain rather than domain_id
- check ring_full first because its value was just evaluated
- check if ring buffer is initialized before calling

Packaging Xen 4.2.0
Hi all,
I''m trying to update my RPMs of 4.1.3 to work with 4.2.0, but I''m having
some interesting problems with the packaging side of things.

4.2.0 it is being built as /usr/lib/xen/bin/xenpaging.
I''m currently using the following configure options in my .spec:

trouble installing building packages from source using R 2.6.0 on Ubuntu Gutsy AMD64
I have recently upgraded to Ubuntu Gutsy and, for the first time, am

source, not a problem for me in the past with a 32-bit install, I went
the route of using the Debian Etch build. This went smoothly, but I am
unable to update my numerous R and BioConductor packages, getting
non-zero exit status errors on each package. Is

Just an interesting data point
SO, my full load on my core UPS is two Dell R610s, one Sun X4540, one HP

The APC SU3000RM (3KVA) that blew up last week considered this to be
just short of 60% load.
The new Cyberpower PR3000 (also 3KVA), wqhich operates at a 90% power
