Then shut it down, loop mount that new partition, then copy all or tar and untar from the below mount (seems like this one has everything needed). Once that's done, boot with your rescue CD again and install GRUB. Could also try similar with qemu-img converting to raw like https://askubuntu.com/questions/4398/how-do-i-convert-a-multiple-part-vmdk-disk-image-to-qcow2/4598. Then dd the raw img to your HVM partition, and use the rescue CD to install GRUB/make it bootable. > mount /dev/mapper/centos-root turnkey-core.mount ^ alternatively, using > this gives me access to: > > - > -- > > > ls -l turnkey-core.rootfs/ total 76 lrwxrwxrwx 1 root root 7 Jan 17 > 2017 bin -> usr/bin > drwxr-xr-x 2 root root 4096 May 14 2015 boot drwxr-xr-x 2 root root > 4096 May 14 2015 dev > drwxr-xr-x 148 root root 12288 Jun 7 2017 etc drwxr-xr-x 2 root root > 4096 May 14 2015 home > drwxr-xr-x 2 root root 4096 Apr 16 23:01 isolinux lrwxrwxrwx 1 root > root 7 Jan 17 2017 lib -> usr/lib lrwxrwxrwx 1 root root 9 Jan > 17 2017 lib64 -> usr/lib64 > drwx-- 2 root root 4096 May 14 2015 lost+found drwxr-xr-x 2 root > root 4096 Nov 5 2016 media drwxr-xr-x 3 root root 4096 Nov 5 2016 > mnt drwxr-xr-x 4 root root 4096 Apr 21 2017 opt drwxr-xr-x 2 root > root 4096 May 14 2015 proc dr-xr-x--- 11 root root 4096 Jun 7 2017 > root drwxr-xr-x 2 root root 4096 May 14 2015 run lrwxrwxrwx 1 root > root 8 Jan 17 2017 sbin -> usr/sbin drwxr-xr-x 2 root root 4096 > Nov 5 2016 srv > drwxr-xr-x 2 root root 4096 May 14 2015 sys drwxrwxrwt 9 root root > 4096 Jun 7 2017 tmp > drwxr-xr-x 13 root root 4096 Jan 17 2017 usr drwxr-xr-x 2 root root > 4096 May 14 2015 var > > > - > -- -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Re: [qubes-users] Re: CentOS Virtualization From Multiple .vmdk
awokd, what a relief to get some additional help here! The issue is that this CentOS VM was distributed as a learning environment for a specific course I'm taking with software/services/configurations/etc directly tied to the lessons. I need everything to be intact. I've reached the limit of my experience in this process and can find no other material online to help me. Your dd loopback advice exactly fits this step I'm stuck at. I don't know how to make this bootable. Sigh... I wrote an email to linuxrespin.org yesterday pleading for help which has some information for you I dread to paraphrase/reformat so I'll repost here, because I list commands run and output of file/directory structures... This bends my brain. Apologies and thanks for helping with this mess: --- Hi linuxrespin team! I'm desperate and need your expertise. For one week now I've been bashing my brain trying to get this to work and I've reached the end of my capabilities. Can you please help me? 1. I have a CentOS virtual machine which runs perfectly in VirtualBox. The VM is in .vmdk format. *. I run Qubes OS and need to run CentOS as a guest. I need to convert the .vmdk virtual hard drives into a format which Qubes will accept. 2. I've used qemu-img to convert the .vmdk files into a raw image. 3. I've mounted the raw image (LVM) onto a loop device and am able to access the file system. 4. I have zero understanding of how to make an iso / live iso from this. Can you please help me? I've used the guide below to aide me, but the final tool from the author's repository does not work for me. Do you know how I can take the CentOS filesystem I have access to and turning it into a bootable iso? https://www.turnkeylinux.org/blog/convert-vm-iso --- ls -l /media/sf_Linux/CentOS\ 7.x\ 64-bit/ total 54015160 -rwxrwx--- 1 root vboxsf8684 Jun 7 2017 CentOS 7.x 64-bit.nvram -rwxrwx--- 1 root vboxsf 3413508096 Jun 7 2017 CentOS 7.x 64-bit-s001.vmdk -rwxrwx--- 1 root vboxsf 2366242816 Jun 7 2017 CentOS 7.x 64-bit-s002.vmdk -rwxrwx--- 1 root vboxsf 4088070144 Jun 7 2017 CentOS 7.x 64-bit-s003.vmdk -rwxrwx--- 1 root vboxsf 2242772992 Jun 7 2017 CentOS 7.x 64-bit-s004.vmdk -rwxrwx--- 1 root vboxsf 226492416 Jun 7 2017 CentOS 7.x 64-bit-s005.vmdk -rwxrwx--- 1 root vboxsf 786432 Apr 26 2017 CentOS 7.x 64-bit-s006.vmdk -rwxrwx--- 1 root vboxsf 720896 Apr 26 2017 CentOS 7.x 64-bit-s007.vmdk -rwxrwx--- 1 root vboxsf 3080192 Jun 7 2017 CentOS 7.x 64-bit-s008.vmdk -rwxrwx--- 1 root vboxsf 720896 Apr 26 2017 CentOS 7.x 64-bit-s009.vmdk -rwxrwx--- 1 root vboxsf19136512 Jun 7 2017 CentOS 7.x 64-bit-s010.vmdk -rwxrwx--- 1 root vboxsf 131072 Apr 26 2017 CentOS 7.x 64-bit-s011.vmdk -rwxrwx--- 1 root vboxsf1029 Jun 7 2017 CentOS 7.x 64-bit.vmdk -rwxrwx--- 1 root vboxsf 69 Apr 26 2017 CentOS 7.x 64-bit.vmsd -rwxrwx--- 1 root vboxsf2888 Jun 7 2017 CentOS 7.x 64-bit.vmx -rwxrwx--- 1 root vboxsf 272 Apr 26 2017 CentOS 7.x 64-bit.vmxf --- qemu-img convert -f vmdk turnkey-core.vmdk -O raw turnkey-core.raw mkdir turnkey-core.mount loopdev=$(losetup -s -f turnkey-core.raw) kpartx -a $loopdev --- ls -l /dev/mapper/ total 0 lrwxrwxrwx 1 root root 7 Apr 16 21:06 centos-home -> ../dm-5 lrwxrwxrwx 1 root root 7 Apr 16 21:06 centos-root -> ../dm-2 lrwxrwxrwx 1 root root 7 Apr 16 21:06 centos-swap -> ../dm-4 lrwxrwxrwx 1 root root 7 Apr 16 21:06 centos-var -> ../dm-3 crw--- 1 root root 10, 236 Apr 14 23:39 control lrwxrwxrwx 1 root root 7 Apr 16 19:03 loop0p2 -> ../dm-1 lrwxrwxrwx 1 root root 7 Apr 16 19:34 loop1p1 -> ../dm-0 lrwxrwxrwx 1 root root 7 Apr 16 19:34 loop1p2 -> ../dm-6 lrwxrwxrwx 1 root root 7 Apr 16 21:06 loop3p1 -> ../dm-7 lrwxrwxrwx 1 root root 7 Apr 16 21:06 loop3p2 -> ../dm-8 --- mkdir turnkey-core.mount mount /dev/mapper/$(basename $loopdev)p1 turnkey-core.mount ^ the above command gives me access to: --- config-3.10.0-514.16.1.el7.x86_64 config-3.10.0-514.2.2.el7.x86_64 extlinux grub grub2 initramfs-0-rescue-0a268e711a9e49e6958dee98a83bcef2.img initramfs-3.10.0-514.16.1.el7.x86_64.img initramfs-3.10.0-514.16.1.el7.x86_64kdump.img initramfs-3.10.0-514.2.2.el7.x86_64.img

Another thing you might try is to create the HVM, then dd your loop device straight into the new HVM's root LVM partition (as long as what's in loop is already a bootable partition with GRUB). Be careful to not dd to the wrong one. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Re: CentOS Virtualization From Multiple .vmdk
Drew,
Would you mind walking me through this more step-by-step? I've tried many
variations of this and I keep failing. I'm using Qubes 4.0. To create the
centos qube I do:
Qube Manager->
Qube->
Create new qube->
Name and label: centos red
Type: Standalone qube not based on a template
In a qube named TEST-VMDK, I have the CentOS root image here:
/home/user/root.img
Which I've created using your advice:
qemu-img convert {path/to/vmdk}CentOS\ 7.x\ 64-bit.vmdk root.img
Is this the correct way to create the StandaloneVM I need? Should it be/not be
based on a template? Should it be the default (PVH) mode, or HVM? Should the
kernel be the default (4.14.18-1) (current)? I don't know how to do this from
the terminal using Qubes 4.0.
>From dom0 I've:
qvm-run --pass-io TEST-VMDK 'cat /var/lib/qubes/appvm' > /home/user/root.img
I think this is wrong? Why does my PVH/HVM show up in /var/lib/qubes/appvms?
Why do none of the qubes in that directory contain root.img? Where should my
root.img reside? Is there a command to create the correct VM type and load a
root image from a specified qube such as TEST-VMDK?
When I do:
qvm-prefs-centos
There's no line about a root.img so I must be doing something very wrong?
As you can see... a lot of step-by-step hand-holding would be amazing. I really
need to understand how to do this. I have a lot of VMs I need to load this
way...
Thank you so much for your help.

[qubes-users] Re: CentOS Virtualization From Multiple .vmdk
1. Create the HVM.
2. use CLI and browse to the directory.
3. Run:
# qemu-img convert {path/to/vmdk}CentOS\ 7.x\ 64-bit.vmdk root.img
This does work. I have done it many times.
