    We are proud to announce the release of the first beta of our Proxmox VE 4.x family - based on the great Debian Jessie.

    Please help us reaching the final release date by testing this beta and by providing feedback.

    A big Thank-you to our active community for all feedback, testing, bug reporting and patch submissions.

    So what's new in Proxmox VE 4.0 beta1?

    New Proxmox VE HA Manager for High Availability Clusters


    The brand new HA manager dramatically simplifies HA setups – it works with a few clicks on the GUI, test it! And it elminates the need of external fencing devices, watchdog fencing is automatically configured.

    Linux Containers (lxc)
    The new container solution for Proxmox VE will be fully integrated into our frameworks, e.g. this includes also our storage plugins. And it works with all modern and latest Linux kernels.

    DRBD9
    We already included the brand new DRBD9 stable release, so its ready for testing!

    Is there now support for USB 3.0 & 3.1 KVM passthrough?

    this is worth celebrating! (or at least the stable release)

    are there any changes to the rest api or pvesh for kvm users? we dont use containers. our tools ssh to the host and run pvesh commands.

    just curious, if you depricated openvz in favor of lxc, why the custom kernel?

    The kernel is the Ubuntu Kernel.
    There are only changes in the api and pvesh, what has to do with lxc, openvz and ha.

    I remember the terrible old days when Proxmox used Debian kernel... lots of compatibility issues with RAID controllers. Then you went to RH kernel and things went much better.
    Why Ubuntu kernel, since server hardware is usually certified to work with RH kernel (and not Debian or Ubuntu specific)?

    Because it's newer, and vendors simply don't test other kernels. If you have any info on how RH kernels are actually better, let me know.
    Meanwhile: https://git.proxmox.com/?p=corosync-pve.git;a=commit;h=3b3cd2bfc5d44834cf9b396cf6303301dae63ba1
    These days it's: newer kernel = fewer bugs to work around.

    We now use LXC, and Ubuntu provides newest kernels tested with LXC. They plan to use kernel 4.1 for release 15.10,
    and we also plan to upgrade to 4.1 asap.

    This is simply not true. IBM, Dell, and HP all have certified their server grade hardware for Ubuntu LTS so if Proxmox is based on the Ubuntu LTS server kernel the support will match Redhat kernels.

    Looking forward to testing the new Containers and the HA option that uses watchdog. HA was the one piece that was difficult to deploy.

    Thanks.

    I saw no mention of multicast on the HA wiki. is this still a requirement?

    according to corosync docs, you can use it without multicast. but then you have to give it a list of all the other nodes.

    Keeping a list would "work", but the whole point of multicast is, well, multicasting to several nodes. A unicast cluster works fine, but if you don't need it, it's mostly a waste.

    The 4.1 Kernel is stable in the meantime. - When will Proxmox switch?

    I saw the installer offers xfs as a Filesystem.
    Can you please write on the advantages /disadvantages for Proxmox?

    Especially: Will it be possible making LXC snapshots with the new
    overlay capacities of xfs in the 4.1 Kernel?

    There is also the network congestion problem where multicast means identical packages are only broadcast once while in unicast the package must be send to each member of the cluster resulting in an order of magnitude more packages over the network.
