Dear All, I am doing a performance study on Xen, and we are deploying Charm++ parallel runtime library as part of our applications. However, we observed a 20% slow down in Xen kernel that was not observed with MPICH. It is very important for us to understand why this overhead is happening. I am guessing that is caused due to the higher cost of system calls like fork and exec, since Charm++

Hi Lamia, Currently there is no direct InfiniBand access support in the Official Xen trees. You might want to have a look at our Xen-IB implementation. A preliminary version can be downloaded here: http://xenbits.xensource.com/ext/xen-smartio.hg Some information about its design and applications can be found here: High Performance VMM-Bypass I/O in Virtual Machines (Usenix 06), and A Case for

The system is Mandrake-9.1 Linux wih gcc-3.2.2. I am trying to compile xenolinux-2.4.24 (with vanilla sources from ftp.kernel.org for linux-2.4.24). The steps of mkbuildtree ARCH=xeno make menuconfig ARCH=xeno make dep produce no errors, but ARCH=xeno make bzImage results in following error messages. Any pointers will be appreciated. -ishwar --- gcc -D__KERNEL__

Hi, I am trying to install Xen/Xenolinux v1.1 on my workstation which has 2 SCSI disks. The first disk has WinXP installed, and the second disk has Redhat 8.0.

Hi all, I manage to create a VM (slackware image) and hide the PCI device (qlogic HBA) from Dom0 to DomainU. Now the Dom0 cant see this HBA and the ''xm list -l'' shows this pci device under the DomainU. But how can I do some scsi inquiry or check if this PCI device is visible to the DomainU from the DomainU''s console. Any help? Thanks and regards Ashit

Hi, I have 2 identical xSeries 346 with 2 identical IBM 72GB scsi drive. What i did is install the centos 4.2 serverCD on the first IBM and set the HDD to raid1 and raid0 for swap. Now what i did is get the 2nd HDD in the 1st Server swap it with the 1st HDD in the 2nd Server and rebuild the Raids. The 1st server rebuild the array fine. My problem is the Second server, after rebuilding it and

Maybe this question is a little stupid, but please help me. I am a newbie to Xen. When I tried to create a new domain "domain 1", I followed the Yan-Ching CHU''s guide on :installing quick file systems for new domains in Xen 1.2". But when I do "xc_dom_create.py -Dvmid=1", Xen seems to start to boot with some normal bootup information, but right after several

Hi, Lately I was puzzled by a vmexit reason 31 which was defined as EXIT_REASON_MSR_READ I allocated an array in xen data section and assigned its MFN to an EPT entry of a domainU, I thought the domU could access this array but after that the domainU crashed and xen gave me this exit reason "Bad vmexit (reason 31)" But there is nothing to do with MSR READ, so I''m confused...

Hello folks I see the EVTCHN driver being initialized as a part of DomainU. XEND (or domain controller) uses the EVTCHN driver to receive notifications for events on the control interface. However there is no XEND (or domain controller) that runs in DomainU. So what is the purpose of initializing EVTCHN driver in DomainU Thanks in advance Nauzad

Hi! I have a opteron machine running in 64bit mode. I would like to set up a Domain0 at 64bit and run 32bit domainU''s on top to use with other 32bit domains in regular x86 boxes for clustering.. Is this scenario possible, considering the use of Xen3 ? TIA -- Miguel Sousa Filipe _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hi All, I am having an issue with an XFS filesystem shutting down under high load with very many small files. Basically, I have around 3.5 - 4 million files on this filesystem. New files are being written to the FS all the time, until I get to 9-11 mln small files (35k on average). at some point I get the following in dmesg: [2870477.695512] Filesystem "sda5": XFS internal error
