Experiences running Nutanix VPC in production?
We are planning a migration from a legacy virtualization platform to Nutanix AHV, using Nutanix VPCs to separate VM networks instead of relying only on traditional VLAN-based segmentation.
The target environment is large-scale, around 1,000 VMs, so we are trying to understand how mature and operationally manageable Nutanix VPCs are in production.
For those already using Nutanix VPCs in production:
- How stable has the feature been in your environment?
- Are most issues diagnosable by the customer, or do they usually require Nutanix Support?
- Are there any design limitations, operational gotchas, or troubleshooting challenges we should be aware of?
- Would you recommend using VPCs broadly for production workloads, or only for selected use cases?
We recently saw an issue where AHV hosts with VPC enabled had host CPU running steadily at 100%. The issue appeared to be with AHV host CPU, not CVM or user VMs. A rolling reboot cleared the condition, but we are still investigating the root cause. This raised some concerns about production readiness and troubleshooting options.
Any real-world experience, lessons learned, or recommended design practices would be appreciated.
Thanks.
