Owel Posted July 11, 2014 Share Posted July 11, 2014 Hi Guys. I'm really new to this whole VM thing. But I have plenty of ideas what I want to do. So I give VM a try. I want to make a new VM from scratch. but it fails. My Machine: Kernel: Linux 3.15.0-unRAID x86_64 Motherboard: ASUSTeK COMPUTER INC. - AM1M-A CPU: AMD Athlon(tm) 5350 APU with Radeon(tm) R3 Speed: 2.05 GHz Memory: 4096 MB (max. 4 GB) Network: br0: - Duplex docker0: - Duplex eth0: 1000Mb/s - Full Duplex Unraid 6b6 What I am doing right now: mkdir /mnt/cache/vm/Ubuntu_VM cd /mnt/cache/vm/Ubuntu_VM qemu-img create cqow2 ubuntu.img 20G wget http://<path-to>/ubuntu-14.04-desktop-amd64.iso qemu-system-x86_64 -hda ubuntu.img -cdrom ubuntu-14.04-desktop-amd64.iso -boot d -m 1024 Then it seems to start, and the console says it starts vnc on 127.0.0.1:5900 but after some time the whole server isn't responding anymore and I have to do a hard reset. I also tried it with Arch - same result. Can you please help me? Is there a guide to set up a VM in unraid? Regards Owel Quote Link to comment
peter_sm Posted July 11, 2014 Share Posted July 11, 2014 Look at the xml file instead below is my CentOS 7 domain file. <domain type='kvm'> <name>CentOS</name> <uuid>ba6891bd-32cf-2236-2525-6e12bb490e9e</uuid> <memory unit='GB'>2</memory> <currentMemory unit='GB'>2</currentMemory> <vcpu placement='static'>2</vcpu> <cpu mode='host-passthrough'> <topology sockets='1' cores='1' threads='2'/> </cpu> <os> <type arch='x86_64' machine='q35'>hvm</type> <loader>/usr/share/qemu/bios-256k.bin</loader> <boot dev='cdrom'/> </os> <features> <acpi/> <apic eoi='on'/> <pae/> </features> <clock offset='localtime'> <timer name='rtc' tickpolicy='catchup'/> <timer name='pit' tickpolicy='delay'/> <timer name='hpet' present='yes'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/vm_disk/KVM/ISO/CentOS-7.0-1406-x86_64-DVD.iso'/> <backingStore/> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source file='/mnt/vm_disk/KVM/CentOS/CentOS.qcow2'/> <backingStore/> <target dev='vda' bus='virtio'/> </disk> <controller type='ide' index='0'> </controller> <controller type='sata' index='0'> </controller> <controller type='pci' index='0' model='pcie-root'> </controller> <controller type='pci' index='1' model='dmi-to-pci-bridge'> </controller> <controller type='pci' index='2' model='pci-bridge'> </controller> <interface type='bridge'> <source bridge='br0'/> <model type='virtio'/> </interface> <serial type='pty'> <source path='/dev/pts/2'/> <target port='0'/> </serial> <console type='pty' tty='/dev/pts/2'> <source path='/dev/pts/2'/> <target type='serial' port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='5900' autoport='yes' listen='192.168.0.190' keymap='sv'> <listen type='address' address='192.168.0.190'/> </graphics> <video> <model type='cirrus' vram='9216' heads='1'/> </video> <memballoon model='virtio'> </memballoon> </devices> </domain> Change the path to HD, cdrom,name of your VM, CPU, memory, VNC listen and bridge name Create a qcow2 images qemu-img create -f qcow2 CentOS.qcow2 30G Start the VM virsh create CentOS.xml After VM are installed, change this line <boot dev='cdrom'/> To <boot dev='hd'/> to boot from from the image, then virsh create CentOS.xml Some virsh commands List domains virsh list Shutdown virsh shutdown CentOS reboot virsh reboot CentOS destroy virsh destroy CentOS To view the details of the VM virsh dumpxml CentOS Start a defined machine virsh start CentOS Enable virsh console on system with Grub2 & systemd nano /etc/default/grub On line GRUB_CMDLINE_LINUX add console=ttyS0,115200 update grub grub2-mkconfig -o /boot/grub2/grub.cfg Enable ttyS0 systemctl start [email protected] Check status systemctl status [email protected] Enable autostart of ttyS0 during boot systemctl enable [email protected] reboot Quote Link to comment

Also my router recognizes a new machine on the network. But I'm unable to connect vnc. Any help? Quote Link to comment
peter_sm Posted July 11, 2014 Share Posted July 11, 2014 What VNC software are u using ? you should connect on192.168.178.11:5900, if this IP is your UnRAID, or try other ports 5901 ..... There are also a way to connect using virsh console CentOS But that needs some tweak on the bootloader for the VM, and also setup tttyS0 on the VM, you can easily google "virsh console ubuntu" //Peter Quote Link to comment
Owel Posted July 11, 2014 Author Share Posted July 11, 2014 I used: realVNC, tightVNC But I'm also using a SOCKS5 proxy. I think this messes things up. I will try it without the proxy when I'm at home. And will google for virsh console Owel Quote Link to comment
