Application Guard Testing with Virt-Manager

·1 min
Virtualization Linux

Received a BSOD with error code 0xc0000225 on a Windows 10 (and 11) VM when enabling the Hyper-V role to do some testing with Microsoft Defender Application Guard. This VM runs on a Rocky Linux host and I typically use Virt-Manager to handle my VMs.

Two changes were necessary to get nested Hyper-V working with virt-manager:

virt-xml <VM-NAME> --edit --cpu host-passthrough

sudo modprobe kvm\_intel nested=1

Note: kvm\_amd for AMD processors

You can check the value here: cat /sys/module/kvm\_intel/parameters/nested

Once that was done, Hyper-V took great, and I could test Application Guard on the VM.

Fedora 11 Beta: First Reactions

Personal Fedora Linux
It seems like just yesterday that I got home from Iraq and refreshed my laptop (Dell Latitude D610). I ran Fedora 8 the entire time I was in Habbaniyah. After getting home, I was excited to get a chance to skip 9 and go right to Fedora 10. I didn’t use it long before I got a new laptop (Dell Latitude D630). Linux never made it on the new laptop. After I read a review of Fedora 11 Beta, I figured it was worth a shot. I downloaded Gparted LiveCD, opened up 20GB of space and popped in the DVD. I split this posting into three sections: the good, the mediocre and the ugly.

Fedora 10. Two days later...

So, I found a way to download, burn and install Fedora. This normally wouldn’t be a big deal but I’m roaming house to house until Rose and I find somewhere to live. I survived Iraq with Fedora 8 and I really wanted to try out the latest. I really enjoyed 8. It was stable and served me well on my journey. But, being the geek I am, I couldn’t resist but install the latest and greatest. And, two days later, I have no regrets. I can honestly say that this is the best distribution I have tried. I used Ubuntu 8.10 as soon as I got home to see what had changed on the Debian front. I wasn’t all that impressed. While it operated smooth, it was missing a few bits which I really wanted. It was lacking the latest OpenOffice.org, Mono and Eclipse and it excluded the Empathy IM package which I wanted to try. It also didn’t have a ready-to-go NetBeans installation in its repositories.

Finding Anonymous Proxies

I ran across a great cgi:perl script for running anonymous proxies. Its called CGIProxy. I have to find creative ways of getting around the different blocking mechanisms while I’m on more locked down networks. Having a little personal proxy running in a few places helps. If you have trouble finding it, I’ve been successful locating builds through its alias: nph-proxy. There are some unsavory types running the code out there, so be cautious with what traffic you send through somebody else’s network/proxy.
