Let me first say, that it does work for Linux guest. It doesn’t work on Windows guest because there is a know bug (/issue) with the default hardware layout – made of i440FX BIOS. VirtManager would not allow us to replace the settings, so we need to create the VM ourselves using XML. You can export your XML settings (of an existing VM) using the command
virsh dumpxml > /tmp/VM_NAME.xml
There are relevant fields there which you might want to save for later, like MAC addresses, network settings, and so on.
You can use this XML file to build your VM anew. Note that you will want to modify the network settings, the name and the UUID. Also – you will need a newer QEMU command (through the package qemu-system-x86), you can find in the Centos updates repository, . It has been providing me with /usr/bin/qemu-system-x86_64 command, which I am using, instead of the default qemu command used by default by VirtManager.
My Windows VM XML file (as a reference you can copy and use) is provided below. Major modifications are required to the hardware settings of the Windows VM – moving from PCI to PCIE, changing from IDE to SATA or VirtIO – and the provided XML gives a good reference of how this file should look like. This was taken from a machine tested to allow USB hot-add/remove via the method provided in my previous post.
Using the GUI, it could be somewhat complex identifying a VM based on its MAC address. There are several solutions on the network using PowerShell, but I will demonstrate it using a simple bash script, below. Save, make executable, and run. Enjoy #!/bin/bash if [ -z “$1” ] then echo “Requires parameter – MAC…
RedHat introduced using modules in DNF on RHEL version 8 (and above). This opens very interesting new options, however, sometimes – a quick-n-dirty repo is needed. An example – for offline systems, a repo of already installed packages (on exactly similar system) is created for later use. This used to work well on RHEL version…
I have been introduced to a very cool software/hardware combination yesterday. It has been, without exaggerating, one of the coolest things I have seen in a while. As you may know, x86 has an issue with scaling up. It’s that x86 architectures and price don’t justify scaling up to tenths and hundreds of CPUs. The…
Lately I have been overloaded above my capabilities. This did not prevent me from doing all kind of things, but most of them are too small to justify a real entry here, so I have decided to make a small collection of small stuff someone might need to know, in order to make it indexed…
ZFS version 2.1.11 is supposed to work correctly with Oracle UEK 7. However, on update (and later – a reboot) – it broke. The driver cannot build using dkms, and the error message is something like this: If you look into /boot/config-`uname -r` output, and look for CONFIG_MODULES string, you will indeed find that it…
Due to a major disk crash, I have had to use my ‘other’ computer for VPN connections. It meant that I have had to prepare it for the operation. I attempted to login to aJuniper-based SSL-VPN connection, however, I did get a message saying that my 64bit Java was inadequate. I had a link, as…
