Nothing on the CPU ties to the cores and type 12, sttable options, is empty... just a handle and the type. I've been silent while waiting for the additional memory since I could not do any real work with only 8G. It finally arrived and I installed it yesterday. I'm very happy to say that my VirtualBox VMs seem to now be working correctly. I've done limited testing, but seen no problems to this point. Much better than an instant system panic when a VM finished loading. On the plus side, with "cpuset -s 1 -l 0-3", things seem reasonably stable. That means no crashes with many hours of use and a lot of compilations. With only 4 cores, it's not a fast as I had hoped, but I will be benchmarking soon. -- Kevin Oberman, Part time kid herder and retired Network Engineer Email: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 --0000000000003ca97605ea6916c7 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div dir=3D"ltr"><div class=3D"gmail_default" style=3D"fon= t-family:tahoma,sans-serif;font-size:small">On Sun, Sep 25, 2022 at 2:48 PM= Tomek CEDRO <<a href=3D"mailto:tomek@cedro.info" target=3D"_blank">tome= k@cedro.info</a>> wrote:<br></div></div><div class=3D"gmail_quote"><bloc= kquote class=3D"gmail_quote" style=3D"margin:0px 0px 0px 0.8ex;border-left:= 1px solid rgb(204,204,204);padding-left:1ex">On Sun, Sep 25, 2022 at 7:08 A= M Kevin Oberman=C2=A0 wrote:<br> ><br> > On Sat, Sep 24, 2022 at 12:07 AM Amar Takhar wrote:<br> >><br> >> On 2022-09-23 22:58 -0700, Kevin Oberman wrote:<br> >> > Thanks, Amar!
