Submission + - XenSource releases product, gets bought by Citrix ( 1

billstewart writes: XenSource has been in the news twice this week — Monday they release a product, then Tuesday they get bought for $500m by Citrix. Here's Network World's take on the buyout and on the product. It looks like the product is packaging new releases of several of their components — there's a 64-bit hypervisor version 3.1 that uses the Intel and AMD hardware tricks, APIs, management tools, and XenMotion, which lets you move running virtual machines around. According to Xen's product page, the free-beer XenExpress version gets the hypervisor, APIs, and some of the management tools, but not the fancier management or XenMotion, and it's somewhat crippled in terms of capacity (max 4 VMs, 2 CPUs, 4GB RAM, while the commercial versions support 128GB total RAM, larger VMs, and unlimited VMs and CPUs.)

(But will it run Linux?) It will run Linux — one of the data sheets implies that Linux only runs in 32-bit mode, while Windows can run 64-bit. Perhaps there's more documentation that provides more details.
