RE: CPU topology
My bad Actually when starting to type in "cpu" - the VM setting appears in a drop-down list - its "cpu.corespersocket" and this is working now - pinning all 8 vCPU's to a single socket Many thanks Gary Gary Dixon Quadris Cloud Manager +44 (0) 161 537 4980 +44 (0) 7989 717661 gary.di...@quadris.co.uk www.quadris.com Innovation House, 12-13 Bredbury Business Park Bredbury Park Way, Bredbury, Stockport, SK6 2SN -Original Message- From: Wei ZHOU Sent: Tuesday, March 12, 2024 9:02 AM To: users@cloudstack.apache.org Subject: Re: CPU topology Hi, Sorry the vm setting name is "cpucorepersocket", not "cpucorespersocket" -Wei On Tue, Mar 12, 2024 at 9:53 AM Gary Dixon wrote: > Hi Wei > > I tried setting cpucorespersocket to 8 on a VM with 8vCPU but it has > still put them across 2 sockets? > > Heres some of the xml output: > > 8388608 > 8 > > 264 > > .. > cores='4' threads='1'/> ... > > Any ideas what I am doing wrong? > > BR > > Gary > > Gary Dixon > Quadris Cloud Manager > +44 (0) 161 537 4980 <+44%20(0)%20161%20537%204980> > +44 (0) 7989 717661 <+44%20(0)%207989%20717661> > gary.di...@quadris.co.uk > http://www.q/ > uadris.com%2F=05%7C02%7CGary.Dixon%40quadris.co.uk%7C2bedeb6f3087 > 41b71ab708dc427325b5%7Cf1d6abf3d3b44894ae16db0fb93a96a2%7C0%7C0%7C6384 > 58309534536696%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2l > uMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C=cy6mSkb1QG87z2H > ws3%2Byj37aiGRnZQLGzyiumeQI3uk%3D=0 > Innovation House, 12‑13 Bredbury Business Park Bredbury Park Way, > Bredbury, Stockport, SK6 2SN -Original Message- > From: Wei ZHOU > Sent: Monday, March 11, 2024 5:29 PM > To: users@cloudstack.apache.org > Subject: Re: CPU topology > > Stop the vm > Add a vm setting cpucorespersocket > Start the vm > > -Wei > > > On Monday, March 11, 2024, Gary Dixon > > wrote: > > > > > > > Meant to have stated here that our ACS version is 4.15.2 Hi > > > > ACS 4.1.2 > > KVM on Ubuntu 20.04 > > Hosts are Dell R7525 AMD EPYC dual socket 32 core CPU’s > > > > Is there a VM setting that can over-ride the CPU topology? > > > > It seems that when we have a VM with less than 8 vCPU – the domain > > xml of a VM shows the CPU topology as a single socket. > > However between 8 and 16 vCPU’s it shows the topology as having 2 > > sockets and 16 or more vCPUs shows 4 sockets. > > I have tried using a VM setting of cpuSocket = 1on a VM with 8vCPU’s > > but it is ignored and continues to use a topology with 2 sockets > > > > BR > > > > Gary > > > > > > [cid:image161185.png@43BB5413.7EEF77E3] > > Gary Dixon > > Quadris Cloud Manager > > [cid:image347717.png@8A941AE6.9AE8C0C0] > > +44 (0) 161 537 4980 > > +44 (0) 7989 717661 > > [cid:image253845.png@DEB7B540.7BE6A036] > > gary.di...@quadris.co.uk<mailto:gary.di...@quadris.co.uk> > > [cid:image058514.png@B54F0EC3.D31BE611] > > http://www/ > > .q%2F=05%7C02%7CGary.Dixon%40quadris.co.uk%7C2bedeb6f308741b71a > > b708dc427325b5%7Cf1d6abf3d3b44894ae16db0fb93a96a2%7C0%7C0%7C63845830 > > 9534544670%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luM > > zIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C=2YFk8YOCHru4RGd > > %2BeW8J2VLdHQ56%2B84er462%2FAo%2Ffxw%3D=0 > > uadris.com%2F=05%7C02%7CGary.Dixon%40quadris.co.uk%7Ca277409825 > > e3 > > 4aaf0d0c08dc41f0e5ee%7Cf1d6abf3d3b44894ae16db0fb93a96a2%7C0%7C0%7C63 > > 84 > > 57750109219152%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV > > 2l > > uMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C=YgDCwDD5fCOV9 > > ZT > > WmqURHVoTP9sNAsxyiqgtn%2FYaAtY%3D=0<https://eur01.safelinks/ > > .protection.outlook.com/?url=https%3A%2F%2Feur01.safelinks.p%2F > > =05%7C02%7CGary.Dixon%40quadris.co.uk%7C2bedeb6f308741b71ab708dc4273 > > 25b5%7Cf1d6abf3d3b44894ae16db0fb93a96a2%7C0%7C0%7C638458309534549780 > > %7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI > > 6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C=UHLpLAIzoWI%2B%2BtEKwLcGD > > 2s5bcukqIIcugHQHPVWnug%3D=0 > > rotection.outlook.com/?url=http%3A%2F%2Fwww.quadris.com%2F=05%7 > > C0 > > 2%7CGary.Dixon%40quadris.co.uk%7Ca277409825e34aaf0d0c08dc41f0e5ee%7C > > f1 > > d6abf3d3b44894ae16db0fb93a96a2%7C0%7C0%7C638457750109228420%7CUnknow > > n% > > 7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLC > > JX > > VCI6Mn0%3D%7C0%7C%7C%7C=jOqpTPry%2FCm4zAUenX2SFUtrfzzt8WF3CgnD > > j% 2FbM2B4%3D=0> [cid:image187233.png@747A4F03.8BAA600C] > > Innovation House, 12‑13 Bredbury Business Park Bredbury Park Way, > > Bredbury, Stockport, SK6 2SN > > > > >

RE: CPU topology
Meant to have stated here that our ACS version is 4.15.2 Hi ACS 4.1.2 KVM on Ubuntu 20.04 Hosts are Dell R7525 AMD EPYC dual socket 32 core CPU’s Is there a VM setting that can over-ride the CPU topology? It seems that when we have a VM with less than 8 vCPU – the domain xml of a VM shows the CPU topology as a single socket. However between 8 and 16 vCPU’s it shows the topology as having 2 sockets and 16 or more vCPUs shows 4 sockets. I have tried using a VM setting of cpuSocket = 1on a VM with 8vCPU’s but it is ignored and continues to use a topology with 2 sockets BR Gary [cid:image161185.png@43BB5413.7EEF77E3] Gary Dixon Quadris Cloud Manager [cid:image347717.png@8A941AE6.9AE8C0C0] +44 (0) 161 537 4980 +44 (0) 7989 717661 [cid:image253845.png@DEB7B540.7BE6A036] gary.di...@quadris.co.uk<mailto:gary.di...@quadris.co.uk> [cid:image058514.png@B54F0EC3.D31BE611] www.quadris.com<http://www.quadris.com> [cid:image187233.png@747A4F03.8BAA600C] Innovation House, 12‑13 Bredbury Business Park Bredbury Park Way, Bredbury, Stockport, SK6 2SN
