no need for pmem, but remember that the image is a full disk, including a partition table
try something like
losetup /dev/loop1 clear.img
partprobe /dev/loop1
as long as your kernel has loop partitions enabled (max_part module parameter as well) this should get you
/dev/loop1p1
/dev/loop1p2
etc
Hi all,
When trying to mount the root filesystem image on a non-clearlinux host
(ubuntu), I get a "wrong fstype" error from mount. (dmesg says "VFS: Can't
find ext4 filesystem".) Do I need the pmem driver on the host kernel in
order to mount/edit the filesystem images?
Thanks!
Sincerely,
Jesse Larrew

Which part of modification/optimization in Clear Container is dependent
on what feature on newer hardware?

Hi Prateek,
Unfortunately, it looks like the demo image was built for newer hardware
(it requires Haswell or newer).

I tried loading these modules using modprobe as well.
Just to clarify, I am trying to run the clear containers demo on an
existing KVM host (so it has VMX), and *not* clearlinux.
Should I try a more recent kernel?
The strace logs when I run the script are here:

This message is telling you that the host kernel does not have the correct
modules available. What distribution are you running? Also, what do the
commands below show?:
$ uname -r
$ grep ^CONFIG_VIRTIO /boot/config-`uname -r`
If you see CONFIG_VIRTIO_NET=m, you can try loading the module:
$ sudo modprobe virtio_net
The same applies for virtio_console. If those options are not listed at
all, your kernel is either too old, or you need to rebuild it so that the
virtio features are either built-in or built as modules to run the demo.
Kind regards,
James.

Hello everyone,
Super excited about Clear Linux, and I have been trying to run the
clear containers demo at
https://download.clearlinux.org/demos/containers/
When I run boot.sh, I get a few warnings, ending with "# KVM session
ended normally.". I cant observe any new containers/VMs.
I am running this on a 3rd generation Intel Xeon E3-1240 V2. Can
clearlinux run on this CPU?
The full output of ./boot.sh is:
---
# lkvm run -k ./vmlinux.container -m 1024 -c 6 --name guest-373
Warning: ./vmlinux.container is not a bzImage. Trying to load it as
a flat binary...
# KVM compatibility warning.
virtio-net device was not detected.
While you have requested a virtio-net device, the guest kernel did
not initialize it.
Please make sure that the guest kernel was compiled with
CONFIG_VIRTIO_NET=y enabled in .config.
# KVM compatibility warning.
virtio-console device was not detected.
While you have requested a virtio-console device, the guest kernel
did not initialize it.
Please make sure that the guest kernel was compiled with
CONFIG_VIRTIO_CONSOLE=y enabled in .config.
# KVM session ended normally.

...and before people ask.. "then why not use the CoreOS one";
we're looking at adding custom extensions in the future, and in addition,
for the super-tiny segment, GO tends to not be quite as nice due to
binary size.

Is there a different scope here from CoreOS is doing with the Go
