If you want to deploy VistA on GT.M on Linux in a virtual machine, my
recommendation would be to consider IO virtualization that supports
virtual machine disks on SAN logical volumes or physical partitions
(such as with iSCSI), and CPU virtualization that supports SMP virtual
machines.
But before you go there, do think about what your objectives are, i.e.,
identify your requirements before you look at solutions.

A New VistA for AHLTA, Redux
By Bob Brewin 02/20/09 04:57 pm ET
I'm picking up strong and high level signals that Veterans Affairs
Secretary Eric Shinseki plans to push the Defense Department to use the
VA's Veterans Health Information System and Technology Architecture
(VistA) electronic health record system instead of the Military Health
Systems Armed Forces Health Longitudinal Technology Application (AHLTA)
system.
Shinseki has made electronic health records, and the ability to easily
exchange health information with Defense, one of his key priorities, and
I'm told he has a meeting with Defense Secretary Robert Gates on Feb. 24
on the topic.
Shinseki, I'm told, wants Gates "to rip out AHLTA and replace it with
VistA." At his confirmation hearing in January, Shinseki told the Senate
VA Committee that he planned to work with Gates to ensure development of
a seamless electronic health records system for active-duty personnel
and veterans, and the meeting on Feb. 24 shows he does not plan to waste
any time on development of a system which serves both departments.
Dr. S. Ward Casscells, Assistant Secretary for Health Affairs, briefly
considered the VistA for AHLTA option last summer, but then said he
favored the "converged evolution" of a system which would jointly serve
Defense and VA.
A Booz Allen Hamilton report in January 2008 said development of a joint
inpatient electronic health records system will satisfy almost all the
requirements of Defense and VA.
Shinseki may have gotten the idea that VistA was a better solution for
Defense than AHLTA during his physical at Walter Reed Army Medical
Center in January shortly before his confirmation hearing. During his
hearing he that he asked two Walter Reed doctors if they were familiar
with VA's electronic health record system, and, according to Shinseki,
they said, "they thought it was an excellent system, and they wished
they had it at Walter Reed."
Hopefully more will be revealed on this subject when I discuss
Defense/VA health information sharing at the Government Executive Health
IT breakfast on Wednesday, March 4 with Rear Admiral Gregory Timberlake,
Director, Interagency Program Office, Department of Defense/Department
of Veterans Affairs. You can register for the breakfast here.
