Need Urgent Help - KVM / Solus VM

Hi,

I am trying to run KVM VPS. Slave has been installed. LVM setup, KVM Bridge setup. I downloaded template from TDN but somehow making machine from it - is showing can not find boot device, HDD is not bootable. Can someone help me troubleshoot it.

UPDATE 1 : Changing generation in template settings worked.
UPDATE 2 : I need help to check the network.

Thanks

    Did you make sure to set the correct partitions to resize in the template config?

  • No, nothing like that, can u explain me please?

  • @Awmusic12635, I was able to change generation of template and now its running. I am still not able to do the network setup.

    For future reference in case this gets on Google for "can not find boot device" on KVM: this usually occurs if (1) the LVM doesn't have enough space for your template to create or (2) you made the template incorrectly, which is what it turned out to be for you.

    As for the network I'll need more information. However, it sounds like you need to properly set up the network bridge. Take a look here and make sure you do eth0/eth1 based on which one you have, and you name it br0/br1 accordingly. Make sure you have IPMI in case you screw it up and have to access the server so you don't lock yourself out. Sometimes you'll do this correctly and you still won't have network on the virtual server. This usually means the DHCP is not running properly.

    In this case, run these commands:

    killall dnsmasq

    virsh net-autostart --disable default

    service dhcpd start

  • @VirMach,

    Yes I followed the same guide, br0 and eth0 are working properly.
    I also see virbr0. If I use realtek as network in settings in solusvm - I also see KVM101.0 kind of network interfaces.

    If you would've used virtualizor you'd be alive and kicking right now :/

    So what exactly is the issue? Can you view the VNC but then have no connectivity on the VPS? Is the VPS properly assigned an IP? Have you checked to see if DHCP is running?

    /etc/init.d/dhcpd status

  • @VirMach : I can view the VNC but no connectivity on VPS. VPS has been assigned static IP by solusvm itsself.

  • DHCPD is stopped, starting it fails. Will i need dhcpd if solusvm is using static IP inside VPS?

    You use paid Solus license? They have quite good support nowadays.

  • Try

    service dnsmasq start service dhcp start

  • /etc/init.d/dnsmasq start
    dnsdomainname: Unknown host
    Starting dnsmasq:
    dnsmasq: failed to create listening socket: Address already in use
    [FAILED]

  • @sdglhm : dnsmasq can not start.

  • edited August 2015

    try killall dnsmasq then

    service dnsmasq start service dhcp start

  • @sdglhm : rebooted VPS after it, network unreachable.

  • That should probably start your dhcp server. Which more likely to solve network related error.

  • @sdglhm : It did not solve the network problem

  • Have you tried contacting solus. They have an awesome support team.

  • what do you get for ifconfig -a?

    you have no IP block? dhcp will not be able to assign IP @darknessends

    if you're using with NAT, internal IPs need to be assigned.

    I hardly think you can blame solusvm because someone does not know how basic networking and bridges work.

    however if you use virtualizor you could be up and running if it takes care of ineptitude for you but then you could end up like this:

    @darknessends give us your full configs, node options screenshots, ip range from solusvm admin panel bridge info etc and perhaps we can help otherwise we are just going to play back and forth all night while you feed us info piece mail.

    Have you tried what I originally suggested already? Do make sure you're running this on the dedicated server and NOT the VPS. Go on the VPS and check out what IP is exactly assigned and if that same IP is assigned to the VPS on SolusVM, with the correct configurations.

    If DHCP still fails to start, check why.
