The changset 21229 breaks Xen 4.0.1 tree on 32bit environment. Starting a guest
VM will throw out an error as "Error: (38, ''Function not
implemented'')". Apparently, the hypercall to mem_sharing_op is
missing for 32bit environment due to 21229. The following small patch can fix
this issue.
Thanks,

The following small patch can fix this issue.This will be the unconditional xc.dom_set_memshr() call in xend''s image.py. Should be wrapped in try-except. -- Keir> Thanks, > -Wei > > > > diff -r afe5a6a8b8df xen/arch/x86/domctl.c > --- a/xen/arch/x86/domctl.c Fri Jul 02 22:04:32 2010 +0100 > +++ b/xen/arch/x86/domctl.c Wed Jul 07 11:51:26 2010 -0500 > @@ -1449,6 +1449,11 @@ > } > } > break; > +#else > + case XEN_DOMCTL_mem_event_op: > + case XEN_DOMCTL_mem_sharing_op: > + ret = 0; > + break; > #endif /* __x86_64__ */ > > default: >_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Should be fixed by xen-unstable:21751 and xen-4.0-testing:21258. -- Keir On 08/07/2010 00:04, "Huang2, Wei" <Wei.Huang2@amd.com> wrote:> The changset 21229 breaks Xen 4.0.1 tree on 32bit environment.
