@@SysGuides I am a freelancer born and living in Germany (Stuttgart). Hope my english is fine enough. I am studying the knowledge you have in your vids because I need this know-how for delivering some services for my middleclass business customers. I am personally specialized in doing jobs for automation tasks in the web browser with selenium web framework and also for functional and performance testing. I am not expert in networking stuff. But I get my customers asking sometimes for these kind of jobs because they trust me but until now I could not deliver them these kind of services. Actually I am looking for someone to whom I could deliver/forward orders. After sawing tons of vids in KZfaq I think you are the right one. I really would like to corparate with you to have win-win relation. How should I contact you to maybe explore a coorparation? Best regards yours Nejat

Thanks for this explanation, i've been setting up windows vm for the past week, and some of the info that you provided was new so i'm also gonna apply it there. The thing that i can't get to work properly yet, is networking. The VM heavily relies on being accessible to other devices in the LAN, so it's pretty important. I need the host OS to have the static ip of 192.168.1.11, and the guest OS to either being DHCP in range of 192.168.1.100-199(that's what my router's default range), or being static ip of something like 192.168.1.80 I've tried lots of things and have been encountering several issues like no internet on the VM, but most often after lots of tries: 1) Host loses it's static ip, and becomes DHCP random address(i guess that's the part of thing that it becomes the slave of bridge0?). 2) Host preserves it's static ip, VM retains it(trying to be as close as possible, it reports as being 192.168.1.112 inside the VM, i guess that's the closest possible free accessible IP of 192.168.1.11), internet inside the VM works, i can access it from other devices, and that's pretty much what i've settled onto, but it feels wrong because it's completely broken. I wish i just could make a virtual network inside the virt-manager with the address of 192.168.1.0/24, but it says it's already used by enp3s0.

@SysGuides 3 ай бұрын

Hi, I'm sorry I couldn't see your comment because KZfaq had blocked it for some "blocked words." Probably because of the IP addresses you entered. Regarding the static IP address on your host for the network bridge, please see my blog post on how to set it. sysguides.com/install-kvm-on-linux#7-08-configure-a-network-bridge As for the static IP address on your Windows VM, you can check this link: www.windowscentral.com/software-apps/windows-11/how-to-configure-a-static-ip-on-windows-10-or-11

I have seen many tutorials on how to setup KVM/QEMU on Linux, and this is by far the best! One question tho: Shouldn't the grub2-mkconfig -o argument be equal to "/boot/efi/EFI/fedora/grub.cfg" in case of UEFI based Fedora? And in my fedora /boot/grub2/grub.cfg is not a symlink to the real file. We would also love to see you guys make a video on how to use SELinux to protect KVM/QEMU VMs against exploits.

@SysGuides 2 ай бұрын

Thank you; I’m so glad you liked it! Do not use the command 'grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg'. Since Fedora 34, there have been changes. More: fedoraproject.org/wiki/Changes/UnifyGrubConfig Regarding SELinux, it has already been taken care of. You can search for SELinux sVirt.

Thanks for the guide, I'm having some troubles and as always its SELinux fault, do you know of the correct way to retag or passthrough a rule or something ? my main troublee its with the `/var/lib/libvirt` whole thing the images and and isos cannot run properly due to SELinux blocking certain executions, which I have checked logs and everytyhing and i'm ok with themn running

Try this command: sudo restorecon -RFv /var/lib/libvirt/ Hopefully, this will resolve the problem.

@archygonzalez3086 5 ай бұрын

And it did @@SysGuides , thanks a lot, still though in the end I decided to restart from scratch, reinstalled the whole system, II had already altered SELinux tags and created other rules that would never make sense. I just finished again the whole walk through and I can almost swear by this guide and your username from now on to all things KVM/QEMU, now it all make sense why it never was actually working ok for me, thanks a lot again, and hope to see more content of yours on the near feature.

@SysGuides 5 ай бұрын

I'm glad it all worked out in the end. I'm sorry to hear you'll have to reinstall the entire system. Nevertheless, in the future, if you ever mess with SELinux contexts and want to reset to default, you can do the following: Open the file /etc/selinux/targeted/contexts/files/file_contexts.local and remove any contexts that have been added by you. Run the following command to relabel the SELinux contexts and repair them on the next boot: $ sudo fixfiles onboot And reboot. Hopefully, it will resolve any SELinux contexts issues.

Thanks again @@SysGuides , literally since thursday I was doing a lot of research on SELinux, but there's not much free, updated, in english and/or spanish out there mostly in Bagheli or Bundeli from rajasthan or bangla =/
