Sorry, I had understood from Gilad that the NUMA fields in the host level are relatively static and the NUMA fields on the VM level are dynamic. I have no problem of having hybrid static/dynamic fields for Host/VM as long as it has a good reason and fully documented :-) > > > Thanks & Best Regards > Shi, Xiao-Lei (Bruce) > > Hewlett-Packard Co., Ltd. > HP Servers Core Platform Software China > Telephone +86 23 65683093 > Mobile +86 18696583447 > Email xiao-lei....@hp.com > > > -----Original Message----- > From: Gilad Chaplik [mailto:gchap...@redhat.com] > Sent: Monday, March 31, 2014 9:31 PM > To: Shi, Xiao-Lei (Bruce, HP Servers-PSC-CQ); Roy Golan; Omer Frenkel > Cc: Eli Mesika; Roy Golan; Liao, Chuan (Jason Liao, HPservers-Core-OE-PSC); > Doron Fediuck; Vinod, Chegu; Liang, Shang-Chun (David Liang, > HPservers-Core-OE-PSC); Yaniv Dary; engine-devel@ovirt.org > Subject: Re: Please help us to review our database schema design with NUMA > feature on ovirt > > adding Roy & Omer. > > why CPU topology is in dynamic? > > Thanks, > Gilad. > > ----- Original Message ----- > > From: "Xiao-Lei Shi (Bruce, HP Servers-PSC-CQ)" <xiao-lei....@hp.com> > > To: "Eli Mesika" <emes...@redhat.com> > > Cc: "Gilad Chaplik" <gchap...@redhat.com>, "Roy Golan" > > <rgo...@redhat.com>, "Chuan Liao (Jason Liao, HPservers-Core-OE-PSC)" > > <chuan.l...@hp.com>, "Doron Fediuck" <dfedi...@redhat.com>, "Chegu Vinod" > > <chegu_vi...@hp.com>, "Shang-Chun Liang (David Liang, > > HPservers-Core-OE-PSC)" <shangchun.li...@hp.com>, "Yaniv Dary" > > <yd...@redhat.com>, engine-devel@ovirt.org > > Sent: Monday, March 31, 2014 3:20:33 PM > > Subject: RE: Please help us to review our database schema design with > > NUMA feature on ovirt > > > > Thanks Eli. > > I will move the vm level NUMA fields to vm_dynamic, and the related > > database schema will be updated accordingly. > > > > Thanks & Best Regards > > Shi, Xiao-Lei (Bruce) > > > > Hewlett-Packard Co., Ltd. > > HP Servers Core Platform Software China Telephone +86 23 65683093 > > Mobile +86 18696583447 Email xiao-lei....@hp.com > > > > -----Original Message----- > > From: Eli Mesika [mailto:emes...@redhat.com] > > Sent: Monday, March 31, 2014 5:49 PM > > To: Shi, Xiao-Lei (Bruce, HP Servers-PSC-CQ) > > Cc: Gilad Chaplik; Roy Golan; Liao, Chuan (Jason Liao, > > HPservers-Core-OE-PSC); Doron Fediuck; Vinod, Chegu; Liang, Shang-Chun > > (David Liang, HPservers-Core-OE-PSC); Yaniv Dary; > > engine-devel@ovirt.org > > Subject: Re: Please help us to review our database schema design with > > NUMA feature on ovirt > > > > > > > > ----- Original Message ----- > > > From: "Xiao-Lei Shi (Bruce, HP Servers-PSC-CQ)" > > > <xiao-lei....@hp.com> > > > To: "Gilad Chaplik" <gchap...@redhat.com>, "Eli Mesika" > > > <emes...@redhat.com>, "Roy Golan" <rgo...@redhat.com> > > > Cc: "Chuan Liao (Jason Liao, HPservers-Core-OE-PSC)" > > > <chuan.l...@hp.com>, "Doron Fediuck" <dfedi...@redhat.com>, "Chegu Vinod" > > > <chegu_vi...@hp.com>, "Shang-Chun Liang (David Liang, > > > HPservers-Core-OE-PSC)" > > > <shangchun.li...@hp.com>, "Yaniv Dary" <yd...@redhat.com>, > > > engine-devel@ovirt.org > > > Sent: Monday, March 31, 2014 12:38:04 PM > > > Subject: RE: Please help us to review our database schema design > > > with NUMA feature on ovirt > > > > > > We put host level NUMA fields in vds_dynamic because these > > > information are from host itself, and NUMA topology may be changed > > > if the host's hardware make a change.
