I have new installed esx 3.5 hosts together with a VCenter Server 2.5.
When I try to install the latest patches via VMware Update Manager, the install worked good up for the first 7 patches.
Between installing the 7. and the 8. Patch I will loose the connection to the esx host.
The only way for me to come out was to reboot the host and remediate again the patches.
Now VUM is installing correct the last 10 patches and (after a reboot) set the esx host to status green toward the baseline.
The error message in VCenter was: An error occured while communicating with the remote host.
Can anyone help me about this strange behaviour?
