What is the limit on how many virtual machines that can be deployed at once? This came up in conversation, where we were considering where to place template storage and what the implications might be behind various choices. which leads to… Limits on Simultaneous Migrations The answer for how many virtual machines can be deployed at once, is closely coupled with the limits on simultaneous migrations. This is because simply put the operations are very… Read More »What is the limit on how many virtual machines that can be deployed at once?

VMware Virtual Machines MAC addresses Occasionally I feel old, today was one of those days. The feeling snuck up on me during a conversation about MAC addresses. Someone mentioned a MAC address starting 00:50:56 and I said with confidence that it was a VMware virtual machine, which prompted the response “how do you know that?”. Which leads us to the topic of this blog post, how did I know that? MAC addresses are not random. … Read More »VMware Virtual Machines MAC addresses
