SEDF tries to satisfy each domain's slice/period specification so long
as they don't violate capacity. For example:

Name                              ID Period(ms) Slice(ms) Lat(ms) Extra Weight
Domain-0                           0      10.0       5.0     0.0      1      0
vm1                                1      10.0       5.0     0.0      1      0

In this case both Domain-0 and VM1 are *guaranteed* 5ms in every 10ms
window, provided they have enough work to do.

For some more info, look under docs/misc/sedf_scheduler_mini-HOWTO.txt

Note that SEDF is no longer the default scheduler.
