Removing Ubuntu 14.04 LTS support in master (4.12 release)

[Wido den Hollander]

Hi,

I've just opened a Pull Requests [0] to remove support for Ubuntu 14.04.

Ubuntu 14.04 will be EOL in 2019 and the current LTS versions are 16.04
(2021) and 18.04 (2023).

Ubuntu 14.04 lacks Java 8 and also has older Qemu and Libvirt versions.

Yet to be implemented/merged functions like Live Storage Migration and
Burst I/O limitation for KVM require more recent versions of Qemu and
Libvirt not provided by Ubuntu 14.04.

Therefor I opened the Pull Request to drop support for 14.04 in the
master branch.

With the 4.12 release happening later this year or early next year we
would be trying to support a Ubuntu release which will go EOL in ~6 months.

The current 4.11 release will support Ubuntu 14.04, so users running
that CloudStack version can keep running their infrastructure.

If there are objections, please post a comment on the Pull Request or if
you agree with dropping the support, please post a comment as well.

How to use ehci usb controller on kvm?

[li li]

Hello guys,

I need to transmit a USB3.0 device to guest VM.

The VM created by cloudstack uses the piix3-uhci controller, so it is 
impossible to identify USB 2.0 or USB3.0 devices in the guest vm.

Is there any way to add EHCI controller to VM by default?


for example

Re: CloudStack DNS names to PowerDNS export

[Ivan Kudryavtsev]

Hello, Community.

Several days ago I wrote about small service that automatically creates
service domain names for CloudStack VMs created. Just would like to publish
small updates which may be interesting to you.

1. The code was updated to use mysql.connector instead for MySqlDb (thanks
to Wido Den Hollander)

2. I have implemented domains support defined for CloudStack accounts,
before - only domain-level DNS suffixes were supported, so, now every
account can have separate DNS zone if it's defined.

3. I have implemented group-based domain names. They may be very beneficial
to those, who create fault-tolerant scalable services with CDNs like
CloudFlare. Now, all VMs created in a single CloudStack group are placed
into a single "group-based" FQDN, so DNS can return multiple A/ records
for a single name. Using this FQDN as CNAME in CloudFlare enables automatic
failover, scalability support without efforts. Just create new VM in the
same group e.g. www and it just works. Want scale down, remove excessive
VMs.

Find more details in Project's README.md
