I have a new ESXi 4.1 installation and I'm having constant issues losing connectivity to the hosts when in vSphere client. The host (and all VMs on that host) will show as disconnected randomly for 5-10 seconds..
This happens several times a day.. I also have issues deploying from templates and vmotioning VMs.. I will get a communication error every once in a while.. I click OK on it and try again and it usually works..
I opened a case with VMware but nothing yet.. He thinks it's DNS related, however, everything looks fine on my DNS servers.. Although there is funky results..
For example.. I have 6 BL490c's.. I ssh into one of them and do nslookups on all 6 ESXi hosts by name and by IP.. When I did this last week, it returned the FQDN on 5 out of the 6 hosts.. On one of the hosts, HOST4, it just returned the name, and not the FQDN..
Today, I did the same thing and it again returned 5 out of 6 hosts FQDN.. However, this time, HOST2 was just the name and not the FQDN..
Both DNS servers that my ESXi hosts point to have valid A records and valid reverse lookup records so I have no idea what to look at now..
Any help would be greatly appreciated..
Thanks
