Platform should be supported by Xen, though it's not implemented yet. My reading of the spec is that
mode='delay' track='guest' corresponds to timer_mode=0 mode='delay' track='wall' corresponds to timer_mode=1 mode='catchup' corresponds to timer_mode=2 mode='merge' corresponds to timer_mode=3
By spec, do you mean xen/include/public/hvm/params.h in the xen sources? That is the only "spec" I can find. If I'm reading the comments in that header correctly, seems your mapping is correct with s/mode/tickpolicy/.
+ "hpet" (libxl, qemu), "kvmclock" (xen, libxl, qemu),
xen supports hpet too, but I don't think xen or libxl support kvmclock.
Agreed.
+ "pit" (qemu), "rtc" (qemu), or "tsc" (libxl).
xen and libxl support rtc too.
They do not support it in <timer> though, do they?
Oh, right. Neither of the drivers support it in <timer>, they simply support setting rtc to localtime or utc, i.e. the offset attribute of <clock>. Regards, Jim
