[RFC] Hypercalls from HVM guests
...QEMU to facilitate event channel handling.
Dom U (HVM) driver changes:
o Modify grant table setup for HVM guest code.
o Modify event channel handling to interface with an unmodified Linux kernel
running as an HVM guest.
o Make misc xen support available as a loadable module.

Xenoprof in an HVM domain
...formance. (HVMs have poor performance? :) ) Being relatively new to
OProfile, Xenoprof, and Xen internals, I would appreciate any pointers,
tips, and comments on how to work the implementation. I see three basic
areas of work.
1. Implement hypercalls in HVM domains. This has been done by Steve
Ofsthun of Virtual Iron who contributed his patches to the xen-devel list
recently. (Thanks, Steve.)
2. Implement the shared buffer that conveys profile events from the
hypervisor to the domain. From my initial crawl through the Xenoprof code
(see for example linux-2.6-xen-sparse/arch/i386/oprofile/xeno...

HVMAssist BIOS boot device problem
Hello,
The xm config option boot="c" is intended to boot from the "first" harddrive; however, the enumeration of harddrives is independent of device enumeration (hda|hdb|hdc|hdd), leading to unreliable boot device selection.
Example A:
I am building a Windows HVM appliance which performs file-system level operations over mounted NTFS volumes - for example a file-system

Paravirtualised drivers for fully virtualised domains
(The list appears to have eaten my previous attempt to send this.
Apologies if you receive multiple copies.)
The attached patches allow you to use paravirtualised network and
block interfaces from fully virtualised domains, based on Intel''s
patches from a few months ago. These are significantly faster than
the equivalent ioemu devices, sometimes by more than an order of
magnitude.

[PATCH - proposed] XI Shadow Page Table Mechanism]
Hi, Robert,
I found out another confusing code snippet:
in void xi_invl_mfn(struct domain *d, unsigned long mfn)
if (ext && pfn < ext->large_page_aligned_size)
According to the code, it should be
if (ext && (pfn>>SPT_ENTRIES_ORDER) < ext->large_page_aligned_size)
If I made any mistake, please point it out.

BSOD "A clock interrupt was not recevied ona secondary processor within the allocated time interval"
Hi,
When dom0 is under heavy load any Vista or Windows 2008 HVM''s that are
running and have multiple cpu''s assigned often BSOD with code
0x00000101 "A clock interrupt was not recevied ona secondary
processor within the allocated time interval"
It only happens if the load in dom0 is high enough to make the mouse
pointer lagged, once the mouse fails to track in
