Could also be an issue if a vendor-specific ISO was used to initially install ESXi. I ran into a similar problem with Dell; I had to get the Dell ISO from their downloads for the specific server model/service tag.
For 6.0 this is fine (you'll use this to get ASNC drivers). You can also add the dell VIB depot to get them this way also.
For 6.7 Dell has (thankfully) stopped shipping ASYNC drivers and moved 100% to inbox. It's all for 3rd party management VIBs. Honestly I've seen 3rd party VIBs be a culprit for updates before. I'd make sure you are updating the BIOS/FIrmware also when updating ESXi (People forget this sometimes).
All of the hypervisors are built for this. It's the storage and clustering that may or may not be built for this. As a rule, highest performance systems are not clustered at all, the can't be. Clustering takes a performance hit.
But in the extreme performance space products like VMware and Starwind are the top dogs. Both have multiple solutions, but they are using tech like memory sharing, localized data, NVMEoF, log structuring, and others to do things that Gluster just can't do. So much so that products like Gluster sometimes use these techs on top to accelerate them (example: Starwind makes a CEPH accelerator platform.)
@scottalanmiller you don’t want a GUI on the virtualization host, ever. Just spin a VM with virt-manager and launch it on your local machine with xming or one of the other solutions in the other comments.
Right, bypassing Windows can be an option, but it's a crappy one. But I got it working directly on Windows, so no need for a heavy VM for one app.
The XCP-NG team is a team that had a horrible business model that they were trying to implement around XenServer (XOA). Great concept, poor business model.
I wish them well but they are fighting a few things...
Citrix couldn't make any real money even when they charged more and people were taking the product seriously.
Last time I checked they were just replacing some management components and packaging some storage stuff. They are not investing in upstream and there's a lot of... changes coming in hardware that are going to require non-trivial investments for hypervisors to remain relevant.
The real problem with Xen is upstream investment is drying up. Citrix has pulled back, Amazon and other cloud providers have moved on to KVM, SuSE doesn't even market virtualization (SAP HANA support, containers, OS is as close to bare metal as they get). Outside of some people in ARM/automotive virtualization I haven't seen anyone picking it up for net new projects. In the enterprise Oracle is the only champion of it these days. KVM won the open source hypervisor war (although at this point does anyone really care?)
Your server has an IP address of 192.168.122.1? Is that correct? Nothing wrong with that technically, but it would be exceptionally unusual. That's almost always the gateway address. What is the address of your gateway?
That's libvirts virtual bridge address for the NAT network.
