Hmmm... this seems to work fine when booting a 32-bit RHEL5 on 32-bit dom0 on 32-bit xen and with 32-on-32-on-64, but fails with 64-bit RHEL5 on 32-bit dom0 on 64-bit xen. Not sure yet if this is a problem with the specific guest instance or what. > -----Original Message----- > From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx > [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx]On Behalf Of Dan > Magenheimer > Sent: Tuesday, February 19, 2008 9:48 PM > To: xen-devel@xxxxxxxxxxxxxxxxxxx > Subject: [Xen-devel] sysfs on hvm guests? > > > Is sysfs expected to work fully in an hvm guest? > > In RHEL5 (2.6.18-based) kernels, the following works native > > /sys/devices/system/clocksource/clocksource0/... > available_clocksource lists the possible clock sources > current_clocksource lists the chosen clock source, > and can be changed on the fly > > but don't work for me from within an RHEL5 HVM guest. > > All reads yield only "jiffies" (which I believe is the > default setting) even though there are other clock > sources available and set, and echo'ing to the > current_clocksource doesn't seem to change it. > > Should I expect that it would work?
