[Dev] Install image fails
by Dwarf Snowcrash
I'm not sure this is the place to post but I don't have any other options.
I followed the instructions for the install pen drive creation and got it to run but was given no choice for a drive to install on. It chose the hard drive without telling me, wiped the drive and failed to install anything leaving me with a boat anchor. I had to install Windows 10, as there was no recovery partition left from the original 8.1 install.
The live image fails to boot.
So far I can't say I'm very impressed.
Any suggestions appreciated.

[Dev] Setting number of cpus
by Pradeep Kiruvale
Hi All,
I am trying to set number of cpus by passing --cpu-shares 1024. I.e to set
one cpu for the container. But its not passing the same value to the lkvm
tool. The lkvm tool still shows as 6. Can you please help me how to pass
number of cpus to a container/lkvm vm?
My docker start script
sudo docker run -ti -m 128M --memory-swap 300M --cpu-shares 1024
busybox:latest
4769 root lkvm run -c 6 -m 128 --nam 0 83000 83036 84672
tried even with
sudo docker run -it --rm busybox:latest --cpuset-cpus=1
same result.
Please let me know what I am missing.
Thanks & Regards,
Pradeep

[Dev] how to find what package is in what bundle
by Long, Paul
Hello-
What is the best way to figure out what packages are included in what
bundles?
Say, for instance, I want to run sar on my baremetal install of Clear Linux
OS for Intel Architecture. I can go to
https://download.clearlinux.org/current/source/SRPMS/ and observe that
sysstat v11.2.0-16 seems to be available in the 5940 release.
Now I can run swupd bundle-add -list on my machine and see all the
available bundles and make a couple of guesses based on what I see there;
maybe it is in sysadmin-[basic|advanced]? Or just sysadmin?
There must be a better way, thanks.

Re: [Dev] how to find what package is in what bundle
by Garcia Naranjo, Jaime
Hi,
In short, there is no easy path to find it out using swupd commands, we are working on this feature and hopefully that will be released soon.
For now the best is (if you’re willing to) inspect manifests files that are included into the release by examining the MoM and then each of child sub manifests.
I.e. https://download.clearlinux.org/update/5940/Manifest.MoM
Jaime.

[Dev] Clear Linux natively as a KVM host w/o OpenStack
by fb.dev.clx
Hi all,
I'm intenting to setup an environment, where I would like to run
virtual machines with QEMU-KVM (independently of OpenStack), with Clear
Linux installed natively.
Clear Linux version:
```
# cat /usr/share/clear/version
5920
```
Clear Linux Bundles installed so far:
```
# ls /usr/share/clear/bundles/
containers-basic
kernel-native
kvm-host
os-core
os-core-update
os-utils
os-utils-gui
```
At first, I tried to run a pre-configured VM with Spice which gave the
following message:
"error: unsupported configuration: spice graphics are not supported
with this QEMU"
I then run the same VM configured with VNC. The VM starts...
```
# virsh list
Id Name State
-----------------------------------------------------
10 VM1000-vnc running
...but I can't manage to find a VNC viewer in the installed bundles.
So, what is the Clear Linux way to get a VNC viewer? Are you planning
to support Spice?
Any suggestions appreciated.
Thanks

[Dev] notes on swupd-client
by Maciek Borzecki
Hi,
I noticed that there's no documentation on how updates are applied by
swupd. I finally got some time to satisfy my curiosity and spent a
couple of hours looking at the source code of swupd-client while making
some notes in the process (included further down this email). Hopefully
someone from the team can comment on their accuracy.
I get the feeling that the update process has been thought through. I
really like the idea that the manifest contains actual HMAC of files
instead of just checksums. I'm slightly concerned about the download
process. If a pack is not available then downloading files one by one
may not be the most efficient, even if HTTP pipelining is enabled. I
guess the preference is just to use packs whenever possible (and the
packs are signed, so that's good :) ).
There are also some obvious concerns (perhaps unjustified) about the
size of staged updates. In case the state directory is on a different
filesystem, the actual size taken by the files is 2 * the update size
(due to extra duplicate made by `tar-tar` dance).
I didn't notice any special handling of updates to swupd, but I also
don't think any special attention is needed here.
I've also pushed the notes to github in case anyone is interested

◊ 1.1.3.1 hash
• every file/manifest/change is identified by HMAC-SHA256
• key computation depends on type of operation/file:
• deleted file: all zeros
• key computed as HMAC-256:
• key is update stat (`struct update_stat'),
• data is xattrs (if enabled) or just empty data
• if xattrs is disabled `key = H(update_stat ++ H(update_stat))'
• same key computation methods for all file types
• for symlink data is the target path
• for regular file, the file contents
• directory, the path

[Dev] Problem testing clear linux

Hello i am having problems trying clear linux, i have burned the
installer image using dd like it is indicated in that link:
https://clearlinux.org/documentation/gs_creating_bootable_usb.html
$ xzcat -v clear-[release_number]-installer.img.xz | dd of=/dev/sdb bs=4M
After that i have two partitions, the first with some kind of
bootloader and the otrher with a basic rootfs, i reboot the pc and
configure the BIOS to boot from the external drive but without
success.
My systema is a Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz
Do i need a system with UEFI to be able to boot correctly? What am i
doing wrong?
Best regards.
