Re: [STABILITY]} Large KVM Infrastructure with ACS

First I thought the problem could be a consequence of over commitment, but per your answers I do not see problems with over provisioning of resources. I would check the MS and KVM agent code, but I believe the problem is number of MS, imagine a singles MS to manage, monitor and orchestrate 250+

Re: [STABILITY]} Large KVM Infrastructure with ACS

2 MS is typical. There is also an issue with starting stopped MS. For example if you start 1MS and within next 30 seconds start the second MS (first MS is loading all hosts), there is a chance they will come up - but really not functional. Specifically sync jobs would fail and status updates

Re: [STABILITY]} Large KVM Infrastructure with ACS

When you say 250+, you mean 250+ host spread in lots of cluster, right? If I am not mistaken, ACS limits the number of KVM hosts in a cluster, something like 50? I do not remember now if that value can be configured, may it can be. I recall to have read something in a Red Hat doc about the KVM

sounds like a bad limit Ilya, i'll keep an eye out. On Wed, Nov 18, 2015 at 10:10 PM, ilya wrote: > I'm curious if anyone runs ACS with atleast 250+ KVM hosts. > > We've been noticing weird issues with KVM where occasionally lots of KVM > agents get Nio connection
