Hi, I have doubt in executing raw.write tests using lxc-execute. When I execute it without lxc-execute it works fine i.e it performs raw.write testing. command :: root at nishant:/home/nishant/Desktop/samba-4.0.0alpha15# bin/smbtorture //localhost/ubuntu -Ubase%base_system raw.write This command works fine. We can see the o/p of this also,

Doing some janitorial (you cleaning the flooded toilets and such) work today. I have come across this line of code that really I''m not sure what the intent was..in xen/include/sched.h #define hypercall_preempt_check() (unlikely( \ softirq_pending(smp_processor_id()) | \ (!!current->vcpu_info->evtchn_upcall_pending & \

For the encryption functionality in the ZFS filesystem we use AES in CCM or GCM mode at the block level to provide confidentiality and authentication. There is also a SHA256 checksum per block (of the ciphertext) that forms a Merkle tree of all the blocks in the pool. Note that I have to store the full IV in the block. A block here is a ZFS block which is any power of two from 512 bytes to

This patch makes "xm info" show information on xen version, compile info, number of socket/core, etc... In order to do that, it extends physinfo hypercall to return number of socket, adds few functions to libxc and extends python wrapper correspondingly. Here is the output of new "xm info": -- system : Linux host : ubuntu xen_release

I''m getting a VFS kernel panic when trying to booting to FC3 from Xen. Its the one that says I must supply a valid "root=" option. (sorry I don''t have it verbatim.) I''m using the xen-2.0 binary installer, kernel 2.6.9. I am using ext3fs, but I am fairly certain that I have compiled support into the kernel. (I''ve tired compile xen from the 2.0

drivers/xen/xenbus/xenbus_comms.c uses full memory barriers to communicate with the other side. For guests compiled with CONFIG_SMP, smp_wmb and smp_mb would be sufficient, so mb() and wmb() here are only needed if a non-SMP guest runs on an SMP host. Switch to virt_xxx barriers which serve this exact purpose. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> ---

Hi all, Here are some benchmarks that I''ve done using Xen. However, before I get started, let me explain some of configuration details... Xen Version SPECjbb WebBench Linux Distribution Debian 3.1 HT disabled Linux Kernel 2.6.12.2 Host Patch CK3s Here are the initial benchmarks SPECJBB WebBench 1 Thread 1 Client 2 Clients 4 Clients 8 Clients BOPS TPS TPS TPS TPS Host

Hi, This patch series fixes the S3 resume of a domain running xenstored and a frontend over xenbus (xen-netfront in my use case). As device resume is happening before process resume, the xenbus frontend resume is hanging if xenstored is not running, thus causing a deadlock. This patch series is fixing that issue by deferring the xenbus frontend resume when we are running xenstored in that same

Directly including ../tools breaks building in separate object tree, as well as building from mkpatch patch (I believe Rik hit that one). This puts xenstore headers in linux-public.

Define resend_irq_on_evtchn() which ia64/xen uses. Although it isn't used by current x86/xen code, it's arch generic so that put it into common code.
