Hi, I''m trying to test some changes of mine to libxc and python/xc.c, does it requires a boot any time I''m trying to test them? What are your development practices? Thanks, David. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Keir: It has been brought to my attention that modular oprofile is broken because it now calls get_vm_area which is not an exported function. This appears to be the result of the changeset that removed vm_map_xen_pages which was only used by oprofile. So we either need to export get_vm_area in Xen, or put that function back. What do you think about this? Thanks, -- Visit Openswan at

hi. trying to understand the idea behind _notify in #define RING_PUSH_REQUESTS_AND_CHECK_NOTIFY(_r, _notify) do { \ RING_IDX __old = (_r)->sring->req_prod; \ RING_IDX __new = (_r)->req_prod_pvt; \ wmb(); /* back sees requests /before/ updated producer index */ \ (_r)->sring->req_prod = __new;

In order to be meaningful and usable together with other measuring methods, their use in my opinion should impose as little overhead as possible. With that, I wonder why per-cpu counters use atomic operations.

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

I''m getting this message (subject line) in daemon.log every time I start or restart xend. I''m not sure if this is related to the fact that I cannot boot up my Windows domU from a VHD file. The Windows domU was working fine with Xen 4.0.0 (with 2.6.32.14 dom0 kernel). When I upgraded to Xen 4.0.1-rc4 (with 2.6.32.16 dom0 kernel), I can no long boot the Windows domU from VHD. The

Hi, I''m trying to run guest pv vm on my machine running xen-unstable (xen-4.0.0-rc3.pre + linux-2.6-pvops). However, I get blktap error: " sudo xm create -c xmexample Using config file "./xmexample". Error: Failed to create device. stdout: unrecognized child response stderr: Check that target "/home/ashish/xen/hd.img" exists and that blktap2 driver

All the resources allocated based on xen_blkif_reqs are global in blkback. While (without having measured anything) I think that this is bad from a QoS perspective (not the least implied from a warning issued by Citrix''es multi-page-ring patches: if (blkif_reqs < BLK_RING_SIZE(order)) printk(KERN_WARNING "WARNING: " "I/O request space (%d reqs) < ring

Folks, The first release candidate for 3.0.4 is ready. Please download and test: http://xenbits.xensource.com/xen-3.0.4-testing.hg The aim is still for final release before christmas. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I have a question about memory page tables in Xen. As far as I understood, every modification to page table will go through Xen(hypervisor). Is it so that all page tables are actually allocated in Xen(hypervisor) instead of guest OS(domain)? Also, is it the case that Xen(hypervisor) needs to maintain a page table for each process running in every domain? Thanks Haifeng

hello, i wonder what command should i used in R to do the modular. right now i have a vector v <- c(3, 4, 5, 6), but i have tried v%2 or v mod 2 or mod(v, 2) or modular(v, 2), and none of these works. Also, how can i find more function command online, i have to search in the mailing list questions, but it is not enough, is that a better website i can search more about R online. Thank you

I presently have a Samba server (3.0.21b) set up as a member server in an NT4 domain (with a real Windows NT4 PDC). We are migrating to an Active Directory domain (with a real Windows 2003 domain controller). We have set up a two-way trust between the old NT4 domain "CLUNKY" and the new ADS domain "SLEEK" (aka sleek.local). The Samba server is a member of the CLUNKY domain

Hi, I have compiled xen-unstable (using hg clone http://xenbits.xensource.com/xen-unstable.hg). I have successfully booted into the dom0 kernel. output of xm list: Name ID Mem VCPUs State Time(s) Domain-0 0 932 1 r----- 591.2 But whenever I xm create, I get: # xm create /etc/xen/domu1 Using config file

I want to find the inverse of an integer k mod p (prime.) Is there a function that can do this for me? I know i could simply write (k^(p-2)) %% p, but i need to do this for large primes (above 100) and this gives the warning message: Warning message: probable complete loss of accuracy in modulus so this method does not work. Any ideas? Thanks, Samuel --

Ever since xen-unstable cset 14308 ("pci back: Fix registration of of filters on subsections of config space") I''ve been getting an MCA on the *2nd* boot of a driver domain using an e1000 NIC. Cset 14308 allowed the proper setup of the PM control registers, so the NIC is put in the D3 power state when the driver domain shuts down. Unfortunately, pci_set_power_state()

Hi to all. I''m installed XEN3.1 correctly but I''m some problem to start it.
