similar to: Strange interrupt data for page fault

Hi, When using lapic as timer source the hypervisor delivers timer interrupts late. In the source xen/arch/x86/hvm/vpt.c function create_periodic_time creates a timer element with a "bonus" of 50% of the desired time until the interrupt: pt->scheduled = NOW() + period; /* * Offset LAPIC ticks from other timer ticks. Otherwise guests which use * LAPIC ticks for

Hi, I''ve played a little bit with the xen scheduler to enhance the performance of paravirtualized SMP domains including Dom0. Under heavy system load a vcpu might be descheduled in a critical section. This in turn leads to even higher system load if other vcpus of the same domain are waiting for the descheduled vcpu to leave the critical section. I''ve created a patch for xen

Hi, we (Fujitsu) are proud to announce the successful live migration of a BS2000 domU (pvHVM). The domU had 32 GB of memory, 8 active vcpus, an active LAN connection and about 2500 FC-disks online. The domU had an active test load on 8 disks running and several cpu intensive test jobs. All BS2000 peripherals are connected via a special pv-driver handling all devices with just one

Hi, we are experiencing significant performance degradation after live migration of hvm domains in Xen 4.0 (SLES11 SP1): after live migration the performance is dropping to less than 90%. I did a backport of cs 23420-23423 and the performance is okay now. I would like to request to include these changesets in 4.0 and 4.1. The backport is quite trivial, I can send patches if you are willing to

Hi folks, i've a question about the ttl, which my wins hook script gets from smbd4wins: I record many entries with extrem high ttls like refresh $SERVER 20 1181977528 $IPADDRS... the ttl of 1181977528 means ~13.000 days which is very long. if i look into the ldb itself, there's an expiry time of ~ 24days (16.06.2007). ---- dn: name=$SERVER,type=0x20 [...] expireTime:

Hello Folks, i'have a problem share a directory to both unix(nfs) and windows(samba). The main problem is, that the rights are associated to winbind groups. the user in question can access the files from windows correctly and locally correctly (via su -$USER). If i mount the directory via nfs and make a su - $USER i can't write to the directory. when calling getfacl $DIR i can see, that

Hi, on a Nehalem system with VT-d enabled we are seeing strange ACPI-Table contents, especially a corrupted DMAR entry.

I'd like to second this question! Also, just in case that it will not become an smb.conf parameter: can't it be added as a comment to the Makefile (probably near the comments to

Hi, this patch passes the orginal cpuid bits for X86_FEATURE_DTES64 (64-bit DS Area) and X86_FEATURE_DSCPL (CPL Qualified Debug Store) to the guest when the BTS feature is switched on.

hello, I would like to map (Read/Write) pages owned by a HVM guest from my Dom0 Linux kernel module. I have access to the "machine frame numbers" of these pages. 1. What is the right interface to do this? kmap needs ''struct page'' ptrs which I doubt exist for pages owned by a HVM guest. Is there a hypercall to do this then? 2. Do I need to modify the HVM behavior in
