    Post [Xen-announce] Xen 3.0.4 released!

    Hi!

    I thought it would be nice to cut/past the announcement here.

    Thomas

    Folks,

    We're pleased to announce the official release of xen 3.0.4!

    This is largely an opportunistic stabilising release for HVM guests, due to
    the large amount of work in that area of the code since 3.0.3. These
    enhancements have in particular improved support for SMP and ACPI Linux and
    Windows operating systems.

    Other highlights of this release include:
    - support for kexec/kdump of Xen and domain 0;
    - graphical framebuffer support for paravirtualised guests;
    - preview support for the new XenAPI management interfaces;
    - enhanced support for IA64 (IPF) and Power systems.

    Since 3.0.4 is an interim release, certain features such as HVM save/restore
    will now be part of Xen 3.0.5 which we expect to release in early 2007.

    You can get the source using mercurial from:
    http://xenbits.xensource.com/xen-3.0.4-testing.hg

    Source and binary tarballs, and RPMs, will be made available from:
    http://www.xensource.com/downloads

    Cheers,

    Now if Xen only had a solution to stop people from binding any IP's they want on their VPS and not allowing you to see all all sorts of traffic within a Xen VM that you should not be seeing.

    Really is a problem when a Xen customer can bind the router IP address on their VPS and take down everyone using that IP address as their gateway.

    Any solutions to those two main problems yet?

    It's quite easy actually... you use a routed config with proxy arp. This makes the host a hop and will only route IP's to the vif's that are in the host routing table.

    It is possible to restrict the IPs of any VPS since Xen 2.0.7 using the anti-spoof facilities of Xen. I don't understand why you are complaining about it, when it's in the network script of Xen since about more than 1 year and a half (and maybe more).

    Just write the following in your xend-config.sxp , and you are good to go:

    (vif-antispoof yes)
    (network-script network-bridge antispoof=yes)

    Note that it works for both bridged and routed VPS, and that also, you need to tell Xen about the IP used by the VPS like this:

    vif = [ 'mac=00:00:01:23:45:67, ip=1.2.3.4 1.2.3.5' ]

    Also, talking about QoS, it's possible to do it on the dom0 of the VPS server, so traffic limiting is NOT an issue either.
