[Bug 1812935] Re: oslo cache mempool issues with python3

2019-04-17 Thread Lorenzo Cavassa
I can confirm it works.

The rocky-proposed package python-oslo.cache-1.30.1-0ubuntu1.1 fixes bug
#1822541 too.

I manually upgraded the n-c-c units on a Rocky cloud (applying the
proper bindings for n-c-c & memcached according with the comment #14 of
bug #1823740) to get the new python-oslo packaged installed and now
n-c-c fully works.

2017-03-24 Thread Lorenzo Cavassa
We ran new tests: some issue shows up even using LXD 2.12

If I run:

for X in `seq 1 4`; do lxc init ubuntu: test$X & done

LXD creates the containers but it can't start them.

This is the output of 'lxc info --show-log test1':

https://pastebin.canonical.com/183666/


If I run:

for X in `seq 1 4`; do lxc init ubuntu: test$X ; done

there are no issues and I can start the containers in the usual way.

Looks like LXD isn't able to handle some sort of concurrency during the
containers creation.

[Bug 1675760] Re: rootfs issues - 2.8 LXD release

2017-03-27 Thread Lorenzo Cavassa
Running the containers 'init' operation in the concurrent way and
looking with a 'top', you can see the related 'unsquashfs' operations
running:

for X in `seq 1 4`; do lxc init ubuntu: test$X & done

top

Waiting until the unsquashfs terminates and then starting the
containers, all is good and the operation runs fine:

for X in `seq 1 4`; do lxc start test$X & done

The 'init' process takes some time to explode the container image on the fs.
Looks like there are not any bugs but all this behaviour is due to the overall 
speed (disk+fs) to unsquash the containers images.

[Bug 1567578] [NEW] libnl should be updated to support up to 63 VFs per single PF

2016-04-07 Thread Lorenzo Cavassa
Public bug reported:

Ubuntu 14.04.4 and SRIOV settings.

As already documented in https://bugs.launchpad.net/mos/+bug/1501738
there is a bug in the default libnl library release installed on Ubuntu
14.04.4

The library release is the 3.2.21-1 and the bug is impacting on the
maximum VFs number that can be enabled (up to 30) even if the PF
supports up to 63 VFs in an Openstack SRIOV configuration

The workaround is to install a newer library release, the 3.2.24-2:

wget 
https://launchpad.net/ubuntu/+archive/primary/+files/libnl-3-200_3.2.24-2_amd64.deb
wget 
https://launchpad.net/ubuntu/+archive/primary/+files/libnl-genl-3-200_3.2.24-2_amd64.deb
wget 
https://launchpad.net/ubuntu/+archive/primary/+files/libnl-route-3-200_3.2.24-2_amd64.deb
dpkg -i libnl-3-200_3.2.24-2_amd64.deb
dpkg -i libnl-genl-3-200_3.2.24-2_amd64.deb
dpkg -i libnl-route-3-200_3.2.24-2_amd64.deb
