Description Adam Jackson 2010-05-21 18:54:41 UTC 
As in the summary: EL6 guests wake up ~100/sec to service an idle pv tablet.  USB autosuspend works just fine, mouse still works afterwards.

We should enable autosuspend for this device by default, as this is a guest density issue for RHEV.
Comment 1 RHEL Program Management 2010-05-21 18:56:22 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 2 RHEL Program Management 2010-07-15 14:38:40 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Guest-wise, is this dependent on a USB 2.0 bus to work?

Currently, we don't emulate USB 2.0, so if we depend on it, this will have to wait a little bit.
