Vmware hot add memory windows 2003

Afterward, I checked whether the change has run smoothly with Task Manager for Windows or using top and lscpu commands Linux. Note that you need to restart Task Manager to see the changes. In Windows Server R2, you can do that right from the window that pops up once you confirm configuration changes.

Note that the NUMA nodes option is grayed out. To be honest, I did not check how adding RAM on the fly affects applications that I was running at that moment. I used the native utilities here apart from sysctl in FreeBSD. I just wanted to show how hypervisor behaves if you attempt changing VM configuration on the fly in an environment that does not support that feature.

Looks as if there were some changes applied! If you know any, please share it in comments. Here, I use lscpu to trace vCPU number change and top for identifying memory changes. Even being said to be capable of supporting Hot-Add, Ubuntu and Debian behave strange. Changing the number of vCPUs also works weird: the system allows hot-plugging, but the newly-added processors are off-line.

Well, this phenomenon has something to do with how Ubuntu and Debian work. Do you have any ideas on how to explain that thing? ESXi Web interface says that everything is great. The system silently allows changing the configuration… but it does not display the right number of sockets until you reboot the VM.

Check out top output. The first and the second outputs were derived before and after hot-adding RAM. Newer virtual hardware isn't supported through this vSphere client. The second way is vSphere Web client. You can use vSphere web client Flash based for configuration of all features of vSphere right now.

This client has everything implemented. It is however still buggy, slow and dependent on Adobe Flash…. This client is still at works, but this feature works well tested. No plugins necessary, no Flash. A very cool way that will be the new management client for the whole vSphere infrastructure. HTML5 host client allows management of single host only, but you can if you run some rogue ESXi hosts or host not managed via vCenter server enable this feature on the VM s if you like.

I know that RHEL is also supported. The virtual hardware section under the Guest OS should read supported. You may be disappointed, but that's the way it is. You need to enable this capability on a per-VM basis in order to use it. Honestly, I don't think that if there is no possibility to hot-decrease RAM, then there won't be much use for this feature.

Windows Server Web Server x Do you know different? If you are aware of other OS's that can make use of these features, please leave a comment below. Follow Simon Long on Twitter. Check out his profile on LinkedIn. Based on that list, nobody will be using the hot add CPU feature then!!

I liked Scott Lowe's approach in his vsphere book. If it needs to be amended on the fly, well you just increase the limit, sort of like hot adding memory. Suppose you could do the same with vCPU's and number of clock cycles.
