VMI is broken under COMPAT_VDSO, as Xen and other non hardware assisted =

hypervisors will be.  I have been working on a fix for this which works =

for older glibcs that panic when the new relocatable VDSO is used.  =

However, I believe at this time that the fix is going to be too radical =

to consider at this stage in the release of 2.6.21.  We don't expect =

this config option to be turned on by vendors for new distributions, so =

at this point we are willing to drop support for it when VMI is compiled =

in, and work on a patch for 2.6.22 which more fully addresses the problem.

Please apply, thanks.
