ennweb / docker-kvm Goto Github PK

Hi,
I've tried to change the smp value but the container won't use more than one CPU core
In the logs I see a warn repeated for [smp value] times:

warning: host doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5]

Hi!

I am impressed of your work. But I have a problem while setting up the docker image.

Startup script:

docker run -v ${PWD}:/data \
    --cap-add NET_ADMIN \
    --device /dev/kvm:/dev/kvm \
    --device /dev/net/tun:/dev/net/tun \
    -e RAM=2048 \
    -e SMP=1 \
    -e IMAGE=/data/win10 \
    -e ISO=/data/win10.iso \
    -p 2222:22 \
    -p 8088:80 \
    ennweb/kvm

Output:

[iso]
parameter: -drive file=/data/win10.iso,media=cdrom,index=2
[disk image]
parameter: -drive file=/data/win10,if=virtio,cache=none,format=qcow2,index=1
[network]
Set 'tap0' persistent and owned by uid 0

dnsmasq: bad command line options: bad IP address

Can you help me in some way? Do I have to configure something on my host system? I tried to commenting out the param --cap-add, but the I receive another error..

Thanks and best,

Hi, maybe I'm asking very stupid questions here, but is it possible to connect via spice? (remote server > https://www.spice-space.org/)

and if yes, how do i do that;-)

I tryed openning poort 3001 to the contaner but cant connect via the remote server.

Also is it possible to hide the VM from the guest? i'm reading something about qemu:arg but i dont understand where to put it in the docker-compose file.

i hope i'n not overasking, thanks!

Using the stock configuration, startup.sh seems to fail to create bridge.conf.

hi, thx for this dcoker . can you add custom NAMESERVERS (args) in docker compose not support "dns" (docker/compose#2847 (comment))?

It would be good to allow setting the password protection for VNC server.
If you don't plan this feature I would like to add it, are you accepting pull requests?

There's no option, from what I can see, to pass a PCI device to the KVM.

I'm not all that familiar with /usr/bin/kvm, but it appears the commands expected are^[1]:

-device vfio-pci,host=01:00.0,x-vga=on \
-device vfio-pci,host=01:00.1

NOTES:

1. I downloaded ennweb/kvm within the past 2 days (28-Sep-2016).
2. I have a working VM who's image was setup independently to include the PCI device.
3. I passed the PCI device, /dev/dri, into the container and it should be ready to pass into the kvm.

FOLLOW-UP:
I don't know if I'll be on the computer much this weekend, but I plan on trying to rewrite the dockerfile or maybe running a second instance of qemu-system-x86_64 and pushing the PCI device manually. I'll share my findings, but it would be nice to get some help with investigating this.

Additionally, thanks for the work to put this together. It's a pretty compact image and I like the interface!

I got the container up and running, but bridge mode always breaks everything. Upon configuring bridge mode I always end up with:

Bridge mode config always ends up with: /startup.sh: line 94: /etc/qemu/bridge.conf: No such file or directory.

Line 94 says:
echo allow $NETWORK_BRIDGE > /etc/qemu/bridge.conf

Not sure what $NETWORK_BRIDGE should contain. Any help would be much appreciated.

After making sure the container can write it's /etc/qemu config file the following problem is:

failed to get mtu of bridge `br0': No such device
qemu-system-x86_64: -netdev bridge,br=br0,id=net0: bridge helper failed
