If you find your NAT Network is not working properly, the first thing you may want to do is list the networks, check their status and make sure the Network is actually started and configured as you expect (eg. is DHCP on and enabled?).
This is a long known, unresolved bug that seems to affect Version 6 randomly and disportionately on especially Mint 20/Ubuntu 18.

Just a quick note and warning is that if you are testing to see if EFIPXE booting works on a VM, MAKE SURE it actually works. For example Iinitially tested using my Distro's QEMU 2.5+dfsg-5ubuntu10.46 and ovmf BIOS firmware (OVMF supports EFI). However, I found on old versions of QEMU (like 2.5), EFIbooting with GRUB NEVER works so it may appear that you have made a mistake when everything is fine when you boot a physi........

When you visit anything other than root things work fine. Eg. if you visit http://testdomain.com/somedirfile.html

I believe from what I've read that this card's driver doesn't support the features after trying all known troubleshooting methods.

This container won't start after exhausting its memory. There are no relevant or helpful messages in dmesg or vzctl.log as well. Standard troubleshooting such as disabling PPP etc has not helped.

I've run into two issues with Lantronix based KVMs on various servers and here's how I solved them (with that said I like these units as they are Java based and OS independent and work very well, unike some other models like Startech).
1.) If you are connected by USB only and you're sure USB support from the BIOS is enabled, you just need to click the following in Lantronix
Interfaces -> Keyboard/Mouse
Check "Force USB Full Speed Mode", this fixed the issu........
This may sound silly but there will be conflicts/issues with the default Centos repository so you have to use a third party like remi (I prefer not to do this but it's the only option unless you migrate your sites/data to another server or can stand some downtime-not an option IMHOon a production server).
You may need to upgrade to PHP5.3 to run Joomla or many other reasons.
Your host needs to use PHP 5.2.4 or higher to run this version of Jo........
One of my test Centos 5 containers was on a partition that filled up and it threw all sorts of errors and stopped responding but now I can't boot it again anymore.
All the console shows is the Linux Penguin on the top left corner and the xm console says "usbcore: registered new driver hub" and has halted there.

Another great way of troubleshooting is booting fro........
NET: Registered protocol family 2
The above is the last thing that I ever saw, I tried pci=routeirq etc.. and it wouldn't work.
The solution is to enable IOAPIC in the VBOX Settings
Just enable "IOAPIC" in the settings for your Centos Guest and you'll find the kernel boots just fine. I wonder if a physical system might stall in this same way if the BIOS has IOAPIC disabled which many people do as a troubleshooting method.

This is what the /var/log/cups/error.log says after my Samsung CLP-310N decided to stop printing. This is a new printer that replaced my CLP-300 and it has been working for a day so far.
What happened is that I lifted the top part (not realizing there were rollers on it) and it stopped printing. The network activity light was flashing ,hitting the stop button didn't do anything. Even powering the printer on and off did not help.
I have restarted CUPS and SMB on the........
