virsh start RDPWindows fails

[TheHighGroundWins]

$virsh start RDPWindows
error: Failed to start domain 'RDPWindows'
error: Network not found: no network with matching name 'default'

[goddard-guryon]

Same thing happened with me, you need to start the network 'default' via systemctl (forgot the exact name of the service, try starting the VM from the virt-manager GUI, it should give a clue about that).

[TheHighGroundWins]

@goddard-guryon
doing $sudo systemctl start libvirtd has allowed the virt-manager to finally open but.
Where should I look for the name of the service. I look around at the details of the virtual machine and in its name seems to be default.

Can you give me more clues to where I can find this mysterious service

Finally found it after scouring through my search history ;) This is what worked for me, give it a try and lemme know if it works for you too

Edit: in case the link breaks or you don't want to open it, here's the codes:

virsh net-autostart default

If it says "failed to get network 'default'" (and virsh net-list --all gives empty list), try this:

virsh net-define /usr/share/libvirt/networks/default.xml
virsh net-autostart default
virsh net-start default

(also try running the commands with sudo and/or rebooting in case it's still not working)

[TheHighGroundWins]

@goddard-guryon
thank you so much. however I have this strange problem were /usr/share/libvirt/ does not have networks even though I do have it installed.

was there any configuration that I was supposed to do that I am not aware of?

[goddard-guryon]

@TheHighGroundWins I'm not really sure what the error is then (coz I'm not a dev of this project :P) Do you have libvirtd service enabled? (in your previous comment you said you "started" libvirtd, but if you haven't "enabled" it, it will be inactive after every reboot; idk I'm just looking for possible mistakes here).

[TheHighGroundWins]

@goddard-guryon enabling it helped but now I'm back at where I started but with a new error
$sudo virsh start RDPWindows
Results in failed to start domain
Cannot access storage file /mnt/W0S/Qemu/RDPWindows.raw no such file or directory

If I do the same command without sudo I just get default is not active.

For some reason I can't activate default with sudo

[goddard-guryon]

Well that seems strange. Check if there's any file in /etc/libvirt/storage. If not create a file there named "default.xml" and add these lines to it (pasting it from the file I have):

<network>
    <name>default</name>
    <forward mode='nat'>
        <nat>
            <port start='1024' end='65535' />
        </nat>
    </forward>
    <bridge name='virbr0' stp='on' delay='0' />
    <ip address='192.168.122.1' netmask='255.255.255.0'>
        <dhcp>
            <range start='192.168.122.2' end='192.168.122.254' />
        </dhcp>
    </ip>
</network>

Then try virsh net-create default.xml (and verify by net-list), and then the same net-autostart and net-start (reboot if needed).
Also, don't run virsh with sudo (I'm guessing that you installed RDPWindows as normal user, in that case sudo virsh can't detect that VM or any config you've made).

[TheHighGroundWins]

@goddard-guryon I still have the same problem.
when I tried to run $virsh net-start default I keep getting:

error: Failed to start network default
error: internal error: Network is already in use by interface virbr0

only way to fix this is by using sudo which you told me not to do.

$virsh net-create default.xml results in :

error: Failed to create network from default.xml
error: internal error: Network is already in use by interface virbr0

if I can just start default without sudo then I think the rest of the problems will fix themselves.

also thank you from spending your time helping me.

[goddard-guryon]

Asa far as I know, virbr0 is what KVM is supposed to use for the network, and if that interface is already in use, there should be a profile present that it is using (are you sure virst net-list and sudo virsh net-list give empty lists?) The only reason I tell not to use sudo is because virsh will not be able to detect RDPWindows in sudo. But if creating the default network with sudo can work, then we can fix it. At this point I'm also not sure how to fix this (maybe try to stop libvirtd, create the xml, then start libvirtd back). If that doesn't work, I'd suggest you reinstall QEMU/KVM via the tutorial given (and after you have created the VM, do the net-autostart command before restarting linux).

[TheHighGroundWins]

@goddard-guryon sudo virsh net-list returns fine. I think that I am lacking some kind of permission which is strange since I am in both libvirt and kvm groups.

I am trying to do this on arch maybe that is why this is not working.
at the end I either get some obscure error from using sudo virsh start RDPWindows which you told me I wasn't supposed to do or I get that the default network default is not active even though default is every much active and autostarted in sudo virsh net-list

[goddard-guryon]

You're on Arch? Check this out and tell me if it works XD

If it's the same issue in your case, then just doing what's written in that comment should let you start RDPWindows without sudo

[TheHighGroundWins]

@goddard-guryon I can finally run the commands without sudo however strangely enough I got the same error when I had tried to run sudo virsh start RDPWindows
when I run virsh start RDPWindows
I get

error: Failed to start domain 'RDPWindows'
error: Cannot access storage file '/mnt/WOS/Qemu/RDPWindow.raw': No such file or directory

[TheHighGroundWins]

@goddard-guryon
your right in the XML file there is the directory with the /mnt
now I just need to find the location of the RDWindow.raw if it even exists that is.

[goddard-guryon]

(previous comment was wrong, I probably misunderstood the problem here, sorry in case you were following it) I honestly don't have much idea about the issue here, can you share the RDPWindows.xml file? My best bet is that you need to reinstall the VM at this point :(
