Cannot create vmware nor virtualbox image after successful build - get_block_dev_from_partition_dev: command not found

[fdimeglio]

Hello,

After building, I wanted to create a VMware or VirtualBox image to be
able to test ChromeOS in a VM. Here is what I got for VMware image
creation:

get_block_dev_from_partition_dev: command not found

I have seen that there has been some recent changes about "Modify
postinstall to avoid x86-specific dependencies. (issue2742009)" with
https://groups.google.com/a/chromium.org/group/chromium-os-reviews/browse_thread/thread/eb2f1ae8504ff01b#

Is it related and how to fix this ?

Thank you,

Fabrice

[Todd Deshane]

I changed the line in src/scripts/fixup_image_for_qemu.py
from:

postinst = postinst[0:m1] + postinst[m2:]

to:

postinst = '. "$(dirname "$0")/usr/sbin/chromeos-common.sh"' + "\n" +
postinst[0:m1] + postinst[m2:]

The missing function call goes away, but the new error is:

ERROR: cgpt add: GptSanityCheck() returned 3: GPT_ERROR_INVALID_ENTRIES

I'm not sure where that is being check/called. This sort of error
might indicated a bigger problem?

Any ideas?

Thanks,
Todd

Thank you Todd.

This issue is tracked with: http://code.google.com/p/chromium-os/issues/detail?id=4351

It seems that we already have a fix proposal. Could you try it and
report your feedback ?

Fabrice

[Mr Seb]

Does that solve the GptSanityCheck error though? Doesn't look related...

(I also have the same problem.)

-S

[Todd Deshane]

I don't think it will fix the GptSanityCheck, since the patch
mentioned just adds the "chromeos-common.sh" and that I just fixes the
original problem.

If I knew where to find more about that I would look into the code
more. Any ideas?

Thanks,
Todd

I looked into a bit more.The problem is a call to install_gpt call
that is made in image_to_vm.sh

The original line was:
install_gpt "${TEMP_IMG}" "${TEMP_ROOTFS}" "${TEMP_KERN}" "${TEMP_STATE}" \
"${TEMP_PMBR}" "${TEMP_ESP}" true false ${FLAGS_rootfs_partition_size}

I changed it to:

install_gpt "${TEMP_IMG}" "${TEMP_ROOTFS}" "${TEMP_KERN}" "${TEMP_STATE}" \
"${TEMP_PMBR}" "${TEMP_ESP}" false ${FLAGS_rootfs_partition_size}

Which fixes the problem. Could somebody double check that I made the
right choice to get rid of the true and not the false?

Must be the install_gpt function had a change in parameters.

This will need to get fixed in the latest vm scripts patch before it
gets committed.

Thanks,
Todd

Will check now -- and also see if vmware/virtualbox boot the GUI (with
USE -opengl)

[Mr Seb]

Boots fine, like previous builds that I've done using the patched
image_to_vm.sh.

Still no GUI with USE -opengl

(Can anyone on the Chromium team suggest how we might get CrOS to run
in VirtualBox/VMware?

-S

[Fabrice Di Meglio]

Well, Todd, your change is strange as I have from "image_to_vmware.sh"
the following which is not the same as yours:

# Set up the partition table
install_gpt "$TEMP_IMG" "$TEMP_ROOTFS" "$TEMP_KERN" "$TEMP_STATE" \
"$TEMP_PMBR" "$TEMP_ESP" true

I updated this morning so I am wondering if you have the latest.

Fabrice

[Todd Deshane]

Hi Fabrice,

Do you have this patch:
http://codereview.chromium.org/2803015/show

(it changes image_to_vmware.sh to image_to_vm.sh, with lots of other
fixes... do ./image_to_vm.sh --help for options).

Todd

This one was just a hack to get rid of the "can't find method X". I
think I patch already went in that fixed this one.

This is the important one though. Was this one fixed in the mean time
on either side of the call?
