it seems I am using tap:aio on what appears to be quite slow:
disk = [ "tap:aio:/disk0/server3.img,xvda,w" ]
Is there a good way to convert from tap:aio to lvm?
Hi Randy,
I don't use LVM and my performance is fine.
Have you looked into the domU itself troubleshooting as if it were a
non virtual host?
Things like vmstat, top, tcpdump, dstat, etc... just to get a
snapshot of what your system is doing.
Apply the same approach to dom0 as well.
I've used both fixed and non fixed disk images w/o issue.
My env is Centos using the bundled version of Xen as well as Gitcos
latest 3.X versions.
