GitHub user gvaishya created a discussion: application vm are crashing in a cluster with mixed CPU model hardware
### problem Problem Description: We have a cluster with mixed hardware and application vm are running with max cpu cycle 2.4GHZ. (example 1 CPU x 2.4 GHz) but recently application has started facing issues that their virtual machines are crashing unexpectedly and they are not able to find any issue at application end. Application type is VDI. Is this issue can be related to mix CPU type in a cluster? Below is the hardware , we are using in a cluster 2 processors, Intel(R) Xeon(R) Gold 6154 CPU (3.00 GHz / 18-core) 2 processors, Intel(R) Xeon(R) Gold 6254 CPU (3.10 GHz / 18-core) 2 processors, Intel(R) Xeon(R) Gold 6148 CPU (2.40 GHz / 20-core) Hypervisor type: KVM =============================================== cat /etc/cloudstack/agent/agent.properties guest.cpu.mode=host-passthrough reboot.host.and.alert.management.on.heartbeat.timeout=false hypervisor.type=kvm iscsi.session.cleanup.enabled=false guest.cpu.features=vmx =============================================== ### versions ACS Version: 4.20.2.0 DB : Maria DB 10.3.39 ACS and KVM host : RHEL 8 Hypervisor type: KVM ### The steps to reproduce the bug 1. 2. 3. ... ### What to do about it?
