Re: [osv-dev] How to compose a vbox platform image with new capstan

[robertob]

I think the problem is that on Fedora there is not "kvm-ok"...so it fails 
for this reason.

I could try to use the code from here:

https://github.com/bannsec/altEnv/blob/master/kvm-ok

 Look at the output of "dmesg" for clues. One common issue is that 
 hardware virtualization is disabled in the BIOS.

Re: [osv-dev] How to compose a vbox platform image with new capstan

[Waldek Kozaczuk]

So I double checked capstan code and here are all conditions it checks to 
set DisableKvm flag 
(https://github.com/cloudius-systems/capstan/blob/efad2dff6ddeded449aa3954bcaefba554a36209/cmd/run.go#L233):
- the 'disable_kvm' flag in ~/.capstan/config.yaml (executing 'capstan 
config print' will show you that) 
- the CAPSTAN_DISABLE_KVM environment variable
- executes kvm-ok 
(https://github.com/cloudius-systems/capstan/blob/efad2dff6ddeded449aa3954bcaefba554a36209/hypervisor/qemu/qemu.go#L319,https://github.com/cloudius-systems/capstan/blob/efad2dff6ddeded449aa3954bcaefba554a36209/hypervisor/qemu/qemu.go#L419)
 
to see if it returns no error

I betting the last check one is somehow failing. Just execute kvm-ok in 
command line using same user you are using to run capstan and see what it 
shows.

Re: [osv-dev] How to compose a vbox platform image with new capstan

[robertob]

I'm still stuck on this problem. KVM works well on the machine but the 
capstan runs the qemu without "-enable-kvm". Is there a way to force this 
parameter in capstan run?

Re: [osv-dev] How to compose a vbox platform image with new capstan

[roberto battistoni]

KVM is installed and working in the system. I enabled all the flags that
Waldek suggested but nothing...the  "-enable-kvm" is not present in the
cmdline.

The capstan version I use is the 0.30.

Any Idea?

Re: [osv-dev] How to compose a vbox platform image with new capstan

[robertob]

I'm using Linux Fedora (Linux version 5.0.7-200.fc29.x86_64):

qemu-system-x86_64: QEMU emulator version 3.0.0 (qemu-3.0.0-4.fc29)


When I run the image through "capstan run" this is the qemu cmdline 
executed:

I do not know how to set accelerator in QEMU.

Re: [osv-dev] How to compose a vbox platform image with new capstan

[Waldek Kozaczuk]

The convert output should go under $HOME/.capstan subdirectory with the 
extension .vbox like so:

```
qemu-img convert -O vdi ~/.capstan/repository/app/app.qemu 
~/.capstan/repository/app/app.vbox
```

If you are using Mac then qemu-img has a bug (
https://bugs.launchpad.net/qemu/+bug/1776920) so you have to use a 
workaround (see https://bugs.launchpad.net/qemu/+bug/1776920/comments/14).

Can you tell us which development platform are you using to play with OSv? 
Laptop with:
- Linux
- OSX (MacBook)
- Windows
on it?

What version of QEMU? What version of VirtualBox?

Depending on it I might give you better advice on which accelerator (KVM, 
Intel HAXM, etc) to use with QEMU.

Re: [osv-dev] How to compose a vbox platform image with new capstan

[Pekka Enberg]

Hi,

I don't think Capstan supports building VirtualBox images, but you can use
the "qemu-img convert -O vdi" command to convert a QCOW2 (QEMU's format)
image to a VirtualBox image.

[osv-dev] How to compose a vbox platform image with new capstan

[robertob]

I made package.yaml that correctly run with default QEMU platform, but now 
I do not understand how to build image for virtualbox platform. When I 
build the image (capstan package compose uni) I see every time that the 
QEMU image was created.

I tried this package.yaml file with "platform: vbox" but noting

name: uni

title: Uni

platform: vbox


require:

- openjdk8-zulu-compact3-with-java-beans

- osv.httpserver-html5-gui-and-cli
