One feature that is really missing at Citrix XenServer compared to VMware vSphere is OS Customization. My dear co-blogger Birk (the VMware guy) will never stop to underline this. At vSphere settings like Hostname, Network configuration, Domain membership, Licensing can be defined in specifications and applied to templates and VM images.
Some days ago, I had a small issue with Citrix Netscaler / Access Gateway Enterprise when I tried to establish a SSL VPN connection.
First, the webpage didn’t offer the Access gateway Client for download and installation when I logged in.
In the current version of vCenter Operations it is not possible to filter events and alarms by the info column, but only by the resource name column. With SQL queries you can workaround that limitation.
During the vCenter installation process you can config a custom http port. This can be needed because of security policies or if a other service uses port 80, but it leads to errors afterwards.
In the vSphere client performance tab of a virtual machine you can monitor the CPU Wait time, but it’s counted for every vCPU and no percentage metric is provided. vCenter Operations can solve that problem for you.
