It''s just about ready -- we''re just working out a few kinks in the blktap2 port. You can expect a new release in the next few days. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

This projects already existed before xen 3.4. What kind of support to high availability,specifically, the version 3.4 has? Xen 3.4 come with Kemari and Remus? I think not, so.

Re: [Xen-devel] High Availability Support in Xen 3.4
If you''re mentioning something that already comes with Xen 3.4, there is none. I guess there is a commercial product, but I''m not that familiar. Regarding the next version of Xen, Kemari is hosting trees which track Xen unstable tree, and we''ve been proposing for integration so far.

No there is no complete HA solution integrated into 3.4 branch. Hopefully this will be a feature for the next stable release. -- Keir On 24/09/2009 03:29, "Rafael Emerick" <rafael.rezo@gmail.com> wrote:> This projects already existed before xen 3.4.

Ok, thanks... But where Xen 3.4 differs of Xen 3.3 in HA terms?

Xen 3.4 has some RAS features -- CPU offlining and memory offlining, and some support for machine-check exceptions. It''s not all really joined together for easy user deployment however. -- Keir On 24/09/2009 22:22, "Rafael Emerick" <rafael.rezo@gmail.com> wrote:> Ok, thanks... > > But where Xen 3.4 differs of Xen 3.3 in HA terms? > > On Thu, Sep 24, 2009 at 4:24 AM, Keir Fraser <keir.fraser@eu.citrix.com> > wrote: >> No there is no complete HA solution integrated into 3.4 branch.
