Hi there, I just saw this morning after mistakenly installing the -amd64 packages on a 32bit machine, that the i386 packages had disappeared from debian from jessie onwards. I was wondering about the reason for this disappearance. Is it because upstream cut off support for 32 bit systems? I scratched really fast on the bug reports and couldn't see one that talked about this. -- Gabriel

Does anyone know if the Xen 3.1.0 kernels as distributed in the "open source" tarballs (x86_64 version) are vulnerable to the recently-announced vulnerability CVE-2007-4573? IF so, is there any plan to release patched tarballs anytime soon? Thanks Steve Timm -- ------------------------------------------------------------------ Steven C.

...hem) like just on any level in the hierarchy - the guest still needs to allocate a full page, even though only the first 32 bytes of it are actually used - the shadowing done in Xen could be avoided altogether by following hardware behavior. Just now I found that there is a resulting issue for the 32on64 work I''m doing: Since none of the entries 4...511 of the PMD get initialized in Linux, and since Xen nevertheless has to validate all 512 entries (in order to avoid making available translations that could be used during speculative execution), the validation has the potential to fail (and...

...i386 hypervisor upstream any more (since Xen 4.3) and hence no more xen-hypervisor-*-i386 packages in Debian Jessie onwards. However the i386 tools still exist (e.g. [0]) and can be used with the xen-hypervisor-*-amd64 package[1] (or via the metapackage[2]) with an i386 kernel+userspace in a "32on64" configuration. Ian.

Hi, I have several machines using xen-hypervisor-3.2-1-i386 from etch-backports and they recently got upgraded to 20 or 24G RAM. I have seen talk of a limit of a 16G RAM with 32bit PAE Xen and indeed this is what I am seeing. I am guessing there is still no way to get the 32bit hypervisor to see more than 16G RAM, and I must go to 64bit. Can I boot a 64bit hypervisor and still keep the same

Hi, --- background ---------------------------------------------------- * what the makedumpfile is: To shorten the size of the dumpfile and the time of creating the dumpfile, makedumpfile copies only the necessary pages for analysis to the dumpfile from /proc/vmcore. You can specify the kind of unnecessary pages with dump_level. If you want to shorten the size further, enable the

.. for both 32-bit apps in 64-bit pv guests and 32on64. This patch depends on more than just guest_context saved/restored as guest state during save/restore/migrate (namely the new fields holding callback addresses). Since the 32-bit kernel doesn''t make use of syscall (it would be possible to do so now, when running on a 64-bit hv), the comp...

...> hosts... That is always good advice if you have a 64 bit processor. The 64 bit version of Xen is recommended over the 32 bit version if you have a 64 bit capable processor. Note that you can run a 32 bit dom0 kernel (and userspace) on top of a 64 bit hypervisor if you like (so called "32on64"). Also with a 64 bit hypervisor it is always possible to run either 32 or 64 bit guests (regardless of the dom0 bit width).

Hi, I am new to virtualization and I am having the obvious hassle of choosing between Xen and KVM. Can Xen experts help me with this? Regards, Arindam _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
