</span>First, check using dmesg or whatever that you do, or do not, have a working HPET within your VM.<br>

If this is a widespread problem, I could concoct a patch to sch_fq which compensates for it. I already fixed the same problem when using part of sch_fq as a basis for part of sch_cake, and demonstrated correct operation on an old, slow PC without an HPET.<br>
