Google Distributed Cloud Hosted 1.9.3 has a known issue where the vm-runtime addon is stuck during the upgrade of the gpu-org-system-cluster from 1.9.1 to 1.9.2 because the kubevm-gpu-driver-daemonset pods are in the CrashLoopBackOff state.


Google Distributed Cloud Hosted 1.9.3 resolves an internal load balancer (ILB) services issue in the UNET component. Releases 1.9.0 - 1.9.2 contained a bug where internal load balancer (ILB) services were assigned an external IP instead of an internal IP. The impact is that the external load balancer IP pool is used more quickly as ILB services take addresses from this pool. However, the IPs assigned to ILB services were not advertised outside of the org, so the service remained internal to the org. This bug is fixed in 1.9.3 so that ILB services are assigned internal IPs.
