It was easy to just move them aside to /lib/tls.old, and current versions of RedHat kernels drop a little file called "kernelcap" in /etc/ld.so.conf.d/ that helps prevent the use of those libraries.i'm using xen 3.1 and i have a 64bit dom0 and 32bit (PAE enabled) domUs (32bit userland and kernels). Do I still need to replace glibc w/ one compiled with -mno-tls-refs in the domUs? I don't get the warning about glibc during the domU boots.No, you don't need to do that.The TLS refs problem happened because 32-bit Xen and glibc both want to do crazy things with the processor's segmentation hardware. 32-bit Xen needs the segmentation for its own protection.64-bit Xen doesn't protect itself using segmentation, so it's not necessary to do anything to prevent a conflict with glibc. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
