Waiting for host to start... (hyperv)

[hinell]

I left this issue open only for a while and will keep several days before closing if nobody gonna report again. I'll reopen it once the problem rise again. If you see the issue is closed feel free to leave your questions below anyway.

SOLVED: At first try to stop using --hyperv-memory cause it is fails to start up your vm even if it is adjusted via hyper-v-manager. Also, you should specify --hyperv-virtual-switch explicitly to allow docker to connect properly. If it still doesn't work then try to remove virtual switch bridge manually via windows network adapters settings and create it once again by using hyper-v manager.

Hangs on when I'm creating new virtual machine.
I followed several similar issues for virtualbox like #3826 but with no luck.

Setup

windows 10 x64
boot2docker - v17.11.0-ce
docker - 17.11.0-ce

Virtual switch is enabled via Hyper-V manager as described here

Steps to reproduce

1 Install docker & Enable hyper-v feature in windows features
2 Enable Virtual Switch
3 $ docker-machine create -d hyperv --hyperv-memory 512 vm1
4 Hangs forever

I also tried to use --debug flag with the same command and got this (clickable) output:

I also tried to remove user/.docker/machine/cache/boot2docker.iso and create vm again but didn't help. The machine hangs anyway.

[knilecrack]

I have the similar issue, except my machine starts and it never gets an IP address, even though I followed everything from docs.

docker --version: Docker version 17.12.0-ce-rc3, build 80c8033
docker-machine --version: docker-machine.exe version 0.13.0, build 9ba6da9

This is on edge, same thing happens on stable.

Although, I noticed I can't run windows containers for some reason, so it looks like something is wrong with my current setup.

@knilecrack
What does sandbox in Virtual-V manager shows? Make & share screenshot please.
Seems like vm can't connect to the network cause have no ip assigned or vm just doesn't start properly.

[knilecrack]

Did you mean this ? https://1drv.ms/u/s!AtmVXevYpYur6j6WHvexC6ShiqkO
So basically I got it to work now, after windows updated to 17063 I completely uninstalled docker everything that I could find (from programdata and from appdata) and reinstalled hyperv using dism.
Only problem now is that it needs like 5-10 minutes to get an IP.
Is there anyway to troubleshoot these connection problems more deeply?

Don't know really. ¯_(ツ)_/¯

I'll close the issue until the problem arises again.

Hi everybody and happy new year.
I am beginner in Docker and I have same problem that you.
I would like to follow the official tutorial of Docker Get Started, Part 4: Swarms

I followed correctly instructions of this page Microsoft Hyper-V

What can I do to resolve this problem ?
Thanks and happy new year again.

@rifton007
Does the problem still persist?
It seems like that the VM started properly but haven't connected to the network.

[knilecrack]

start with --debug option and paste output.

[knilecrack]

hey, if you still have issue, try setting IP address manually in VM. 1st get subnet of the switch by right-clicking on adapter that you are trying to use for VM, choose status and then details and you will see a network and subnet of the switch. Then you can try to assign an IP from that subnet on the machine.

Connect to a VM from hyperv, and then just type: ifconfig eth0 172.27.240.10 netmask 255.255.240.0 (in my case)

let me know if that worked for you, you can check by docker-machine ls

[timothy2005]

I also encountered this issue, and fixed it, I think the root cause is: the document is unclear.
to solve this:
Please make sure you have selected the correct network
There are several networks in the list, but probably there is only one is enabled
You may check the status in: Control Panel\Network and Internet\Network Connections
You may also get here through: Network and Sharing Center/Change adapter settings

See following picture for detailed explanation:

@timothy2005 Thanks for you efforts. 👍 Added link to your solution to the top.

It worked for me! tks

[tahsear]

I faced the same issue. retried from powershell window in admin mode, first vm took around 10 minutes while appeared to be stuck at Starting Vm step but eventually completed the task. second vm was created much faster.

[Fsud]

solve this by NOT add -hyperv-memory！At fitst i set this to 512, but when i remove this, it works.

[roeliman]

my way out, thanks @moviewang
