If a VCS service group has more than one KVMGuest resource monitoring virtual machines and one of the virtual machines is migrated to another host, then a service group level concurrency violation occurs as the service group state goes into PARTIAL state on multiple nodes.
Symantec recommends configuring only one KVMGuest resource in a Service group. See the sample configurations below for reference.
Configuration 1:
group rhev_grp1 ( SystemList = { north = 0, south = 1 } ) KVMGuest kvmres1 ( RHEVMInfo = { Enabled = 1, URL = "https://rhevm-server.example.com:8443", User = admin, Password = bncNfnOnkNphChdHe, Cluster = dc2_cluster1 } GuestName = rhevvm1 DelayAfterGuestOnline = 20 DelayAfterGuestOffline = 35 )
Configuration 2:
group rhev_grp1 ( SystemList = { north = 0, south = 1 } ) KVMGuest kvmres1 ( RHEVMInfo = { Enabled = 1, URL = "https://rhevm-server.example.com:8443", User = admin, Password = bncNfnOnkNphChdHe, Cluster = dc2_cluster1 } GuestName = rhevvm1 DelayAfterGuestOnline = 20 DelayAfterGuestOffline = 35 ) group rhev_grp2 ( SystemList = { north = 0, south = 1 } ) KVMGuest kvmres2 ( RHEVMInfo = { Enabled = 1, URL = "https://rhevm-server.example.com:8443", User = admin, Password = bncNfnOnkNphChdHe, Cluster = dc2_cluster1 } GuestName = rhevvm2 DelayAfterGuestOnline = 20 DelayAfterGuestOffline = 35 )
