Need some advice on Virtualizing a server

Hey All,

 

Need some quick advice.

I have a dedicated server provided by OVH that is currently set up as a cPanel/WHM host on CentOS 6.

 

The server is spec'd as follows

CPU: Intel Xeon E5-1620v2 @ 3.70GHz

RAM: 64GB
HDD: 2TB

 

I was wondering if it'd be worthwhile switching it to a Virtualization platform such as ESXi and running the cPanel server as a guest OS?

 

Right now since it's just a cPanel box it limits what I can do/install on the server.

 

If I do go the ESXi route how would it affect things like SSL, DNS, and IP management (the current server has about 10 IPv4 IP's assigned and a 64 block of IPv6)?

It shouldn't affect those really. You'd want to get an additional IP to manage the host OS, but the other IP addresses could be assigned to the guest (you would bridge the guest network to the network interface on the host, giving it internet access). That way your DNS still points to the same IP addresses as before

Thanks Dave.

 

I'm probably going to be undergoing this transition sometime within February.  Got to actually do a complete backup of all the user accounts and setting on the current server and migrate to a newer OS version at the same time. (because it runs cpanel can't just go from CentOS 6.6 -> CentOS 7 >.<)

      Or, they could really turn the table upside down and rename it in BINARY. 00011001

    • Windows 11 Font Frustration!!!

      By margrave · Posted

      I have tried that registry 'trick' from that video already. It doesn't work at all in Win11 for me   Yes it's a 3rd party app... that I am only using because of Microsoft breaking user customization in Windows 11. So yes... the is a Windows 11 issue. As of now to me, Microsoft has made a huge mistake with this in Windows 11.   The current font option in Windows 11 are terrible. They are just missing. People that want to use their own computer the way they want to, they need to avoid 11.

      How does this accomplish that?

      It's been an age since I did desktop support, but here goes: You have an issue with Windows 11, which is fair.  You are using a freeware 3rd party app to make modifications to the default Windows 11.  Since an update, this 3rd party application no longer plays nice with Windows 11.  And this is somehow Windows 11's fault? Sorry, not buying that this is a Windows 11 problem... it's a customization issue that has just appeared, but standard 3rd party support.   Clearly you're upset.  You can't make Windows do anything, just like you can't make MacOS run Explorer or Linux run Nintendo games natively.  And I know people are going to say "sure, it's possible..." but those aren't defining elements of the OS.  You can't have animated backgrounds in Windows 11 natively -- so it's trash amirite??? I did quick searches about changing the default fonts and there are ways to do it, and clearly 3rd party freeware apps can do it (basically my guess is they're making registry changes on your behalf) and clearly they're having issue.   You can make your computer do a lot of things, but sometimes you get what you pay for. Did a quick search and don't see an easy option in Windows 10 either.  Some of these links - ironically - are for Windows 10.  They still apply. Here's a video tutorial of how it can be done without a 3rd party:   Same reference here with a bit more detail: https://www.howtogeek.com/716407/how-to-change-the-default-system-font-on-windows-10/ Once the font is chosen, the size can be changed via personalization from my understanding. Hope this helps.
