Disk image directory option not in Create KVM Instance, create empty system

Thanks for the reply.

After spending a few hours last night back tracking the code, I found that it wasn’t programed in to support specifying the image location.

I started hoping that the code was there in the background and it just needed to be passed a path, not the case I found out. But here are the notes as to what I did and some other issues that came up. Maybe it will help you when you get to the point of working it in to the 6.5 version.

I’m in the path “/usr/libexec/webmin”.

I took the form element code from “server-manager/create.cgi” and added it to “server-manager/empty.cgi” – as far as I can tell with my limited Perl experience it appears to work.

My current problem is that I keep getting told there is not enough disk space.

I traced that error to the “host_free_disk” function in server-manager/server-manager-lib-funcs.pl This gets the host data from “&get_server_collected($vhost)” which looks ok as far as I can tell.

My problem is that the “host_free_disk” function checks for lvm and if found uses it to determine the drive space, this fails on my current configuration.

I have a USB stick that is my base drive which was configured as an lvm during the install (defaults). I decided since I’m not using raid against expanding the lvm and just to mount my extra drives outside the lvm.

df -ah

File system Size Used Avail Use% Mounted on /dev/mapper/vg_vserver-lv_root 13G 1.8G 11G 15% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys devpts 0 0 0 - /dev/pts tmpfs 16G 0 16G 0% /dev/shm /dev/sdc1 485M 52M 409M 12% /boot /dev/sdb1 2.7T 201M 2.6T 1% /storage_one /dev/sda1 2.7T 201M 2.6T 1% /storage_two

This causes the “host_free_disk” to fail with not enough disk space.

This problem actually drifts over to the “Create working system” also as I am unable to create those because of the above function not detecting the drive space – even though I’ve specified a location using the “Disk image directory”.

Now all the above still doesn’t cover if the vm disk is created or not or the actually using the “Disk image directory” to make them.

That is as far as I got as it was getting late and I had enough fun for the night.

On side note on the “Create working system”, you might want to work in an error or warning that you need to download a system image in “Couldmin Settings > New System Images” before using the “Create working system” form.

When you don’t have an image downloaded the form does not show the “Cloudmin system image” select option, since there is no system image available. But it also doesn’t tell you until you submit the form.

Then it’s a bit confusing as it say something like no system image specified – but you go back to the form and there wasn’t any place on the form to specify one.

Anyways, hope this helps some.

I’m going to wipe and reinstall without the lvm and see if I can use the system image to create the machine then reinstall over it.

It appears that I cannot create any system images because of the volume group space check. I reinstalled and removed the volume group from the drive, but cloudmin still only reported the default usb stick size, ignoring the other drives - even though i specified a image directory in the create form.

Just thought I'd pass that note along ...
