After some time using VMWare Workstation as a playground for my VM home lab environment, and after learning and testing with VM ESXi Hosts, I decided that is time to move to a hardware lab. So I achieved, for the start, 2 servers for the ESXi hosts, and because there is no HDD on the servers, I have installed the ESXi software on an USB Stick. For the storage I
In today’s post we’ll see what is EVC, in which case is needed and how we can enable it on VMWare cluster. What is EVC Let’s see first what is EVC – source VMWare: EVC stands for Enhanced vMotion Compatibility. This is a vCenter cluster feature which simplifies vMotion compatibility issues across CPU generations. EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible
I had to upgrade vCenter from 6.0 to 6.5. It’s not the first one, I made a few recently cause we have a client with many sites that should be upgraded. Everything was good prepared or at least I was thinking so and I was ready to start. In the evening, after the working hours as it was planned, I’ve started and quite soon, at the 3rd step of stage

Then I’ve connected to vCenter and look after the name. No VM with this name in the cluster. I’ve contacted my colleague and asked him to send

As you can see, my problem is with VMWare vSphere PowerCLI
Working with VMWare it’s a continues challenge, with new surprises every day, but fortunately, so far, only with happy endings. Let’s see today’s story. I am working for a client that has a vCenter with 6 ESXi hosts. In order to access it, I have to start a VPN, then connect to a Windows terminal server via RDP and from this machine again via RDP to another Windows terminal server.
After upgarding VCSA to version 6.5 at one of my clients, I’ve tried to upgrade also the ESXi Hosts. I’ve made the Baselines in VUM and attached them to the hosts. So far everything went smooth. After that I’ve scanned the hosts for updates and this is the moment when the error came up: “Host cannot download files from VMware vSphere Update Manager patch store. Check the network connectivity and
Use this procedure to reset the vCenter Server Appliance Administrator (email@example.com) password. You will need the vCenter Server Appliance root user credentials. Step one – connect to vCenter Server Appliance Using putty or an OS with ssh support, connect through SSH to the vCenter Server Appliance console with the root user credentials Step two – Start service tool For vCenter 5.x, run the following command: /usr/lib/vmware-vmdir/bin/vdcadmintool For vCenter 6.0 and
