Dear R-help listers, I am now asking for helps on how to draw stacked ellipses to illustrate the shared and specific of multiple objects using R. My problem comes from my population genetics study. Now, I genotyped three species, and I get known about the amount of shared and specific haplotypes in each of the species and their combinations. I want to illustrate this result in three stack ellipses, with the shared and unique area of the stack ellipses were annotated with the relative amount. my data is as followed: ------------------------------------------------------------ hap....

This patch changes hap parameter from boolean to integer. So users can disable and enable hap using "hap=0" and "hap=1". It also prints out nested paging message under SVM. Signed-off-by: Wei Huang <wei.huang2@amd.com> _______________________________________________ Xen-devel mailing list...

This patch initializes VMCB CR4 and shadow CR4 with 0 when VMCB is being constructed under nested paging mode. It complies with recent reset_to_realmode change in hvmloader.

...s and it is getting complicated. I can just xen not do any TLB management and let the guest just do it after return from the hypercall. That would be simpler than hacking xen further to put in hooks for hybrid. However, before doing that, I am wondering if there is even a usecase for hybrid without HAP. The only case I can think of is dom0. For backend grant frames mapping with autoxlate/HAP, it would need to update the HAP for every frame, and don''t know if that would be a significant overhead. If not, then we don''t really have a use case for running hybrid autoxlate off, and n...

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each

Hi Everyone, I am running 3.2.1 on Centos 5.2 with HAP enabled, NUMA enabled, ACPI enabled and the dom0 allocated 512Mb. I have setup a single core 1Gb VM for performance testing under Windows 2008 Server. Most CPU results are within a few percent of theoretical max but Memory performance is about half what I expected. I get 3.22Gb/Sec Sandra 2009 Mem...

Although HVMOP_track_dirty_vram is called many times from qemu-dm which is connected via VNC, XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY is called only once from a migration process (e.g. xc_save, libxl-save-helper).

...e the Debian wheezy kernel is just a bit too ancient. The 3.8 kernel from experimental works on bare metal, but when booting as dom0 under the xen hypervisor it crashes. I just figured out how to redirect xen output to my IPMI/BMC serial port and I see this: (XEN) HVM: Hardware Assisted Paging (HAP) detected (XEN) HVM: HAP page sizes: 4kB, 2MB (XEN) Brought up 4 CPUs (XEN) *** LOADING DOMAIN 0 *** (XEN) elf_init: not an ELF binary Does this mean that Debian is compiling the kernel incorrectly (in which case I''ll file a bug), or is my Xen now too old to support it? Thanks James

I realized that I had failed to cover the hardware assisted paging case in my earlier p2m_ram_ro patches. This should fix it. Note that I say "should" - I don''t actually have an NPT or EPT capable box to test this patch on, so treat it with a modicum of caution. :) The patch also contains an update to the comment for the p2m_ram_ro type, so that it describes the current

Can some one throw light on this. Regards -S.Balaji

Thanks for this. I''ve commented on patch 4 (core) and patch 12 (hap-on-hap) separately. Also I think we need an Acked-by: from Eddie for patches 1-8. Apart from that I think we can check these in as soon as the 4.1 branch has been taken, and fix up any remaining issues in-tree.

When I hit https://<the site> The user gets a warning saying that site identity could not be verified and the user can add an exception if they want. How do I stop this from happing? Do I need to buy an SSL cert? Aren't these really expensive per server and I have 5 servers I would need to do this too. Can anyone provide advice? -Jason

Dear Johnny, Yes, I have tried much larger numbers than 60 and 3 for the above two parameters respectively. And I am sure it is using ?protocol 2? because it?s uncommented in sshd_config. Is there a way to catch what?s happing before quit? I couldn?t see anything except for the line ?write failed, broken pipe?. Thanks.

All servers got updated, but only two of them did the rewrite. Any ideas as to why it might have happed, or how to make sure it doesn't happen again? Hopefully nothing so simplistic as "exclude bind from auto updates" though if that's the only answer, we'll take it. Thanks.
