Here’s another installment of ‘Quick Bits’:

• There’s an interesting conversation taking place over on Scott Lowe’s blog. He posted some thoughts from a recent meeting with some Citrix folks which covered XenServer. Simon Crosby, from Citrix (formerly XenSource), posted an extended version of his comment response over on his Citrix blog. There seems to have been some mis-information on both sides, but I recommend you check out the discussion.
• Another response by Simon Crosby in regards to a post by a VMware employee on cpu checking during the live migration of VMs. More of the same.
• VMware released five new performance white papers. I haven’t fully digested it yet, but one of the white papers covers VMI (VMware’s paravirtualization) which lines up nicely with Scott’s XenServer discussion. You can see a summary of all five white papers (with links) here.
• As mentioned in Quick Bits #1, Andrew Kutz has done some good work in relation to VirtualCenter plugins. He recently posted the first revision of his “VMware Infrastructure 3.5 Plugin and Extension Programming Guide”. You can check out the two plugins he’s created and the guide here. Keep in mind that 3rd party plugins are currently not supported by VMware.
• VMware launched a Developer Center blog. So far there is a single ‘welcome’ post (with some brief info), but hopefully we’ll see some good info coming from it. You can find the blog here.
• Via Duncan from yellow-bricks.com, VMware published a KB article which details how to get a shell on a running instance of ESX 3i. The shell is intended to be used in tech support situations. You can find the KB article here.

As always, feel free to post your thoughts in the comments below.
