Hi, I''m trying to build a xen-qemu-dm-4.0 package to support the HVM part of the Xen 4.0 package that will be soon in Debian experimental. When I start an HVM domain, I have the following subject line of this thread in my /var/log/xen/qemu-dm-XXXX.log file, and then it stops here. Any idea what I should do to fix? Thomas P.S: my build is using a clone of

Hi Everybody: I am trying to get virt-install to work with a kickstart file that is on the local file system. I tried using the --initrd-inject="/tmp" --extra-args="ks=file:/myks.cfg" but I got this error message: ERROR --extra-args only work if specified with --location. Here is the basic command: virt-install \ --accelerate \ --cdrom

Hi, I don''t want to hijack this thread. But as I lately posted a question which mainly was about weight and cap and this fits in perfectly (and also you seem to be an expert here), I repeat it below. In the meantime I saw an academic article Ludmilla Cherkasova et al. from which I understood that you have to careful that a Dom0 doesn''t get too much weight, as otherwise

Hello all ;) Tell I have a Xeon server with 4 vcpus If on this box I have some guets, tell 10, what is the best solutions : - Set all guests to 1 vcpu ? - Set all guests to 4 vcpus ? I well understand that if I set a guest with 4 vcpus and all others only with one vpcus, then the one with 4 vcpus will have more "cpu time" available than others guests. But in case I''d like

Hi, I''m a PhD student trying to add some load balancing code to the credit scheduler in order to fit some specific necessities. I''m trying to understand the credit scheduler code and I don''t quite get in which part of it a pcpu starts running a vcpu. I need to keep track of when a vpcu starts running in a cpu and when it stops. Any hint on that? I think that it would

hi, i am trying to find out the max vcpus supported for any domain by my hypervisor, however i am having some trouble with the below: vcpu=5 maxvcpus=libvirt.virConnect.getMaxVcpus(conn,'kqemu') if maxvcpus <= vcpu: logging.debug('checkmaxvcpus: max vcpus on hypervisor %i is less than requested vcpu of %i' % (maxvcpus, vcpu)) return 0 else: return 1

Hey. I have a very annoying problem, and was wondering what is wrong. Suppose I have backgroundrb running, and then I have an action in some controller. In the action I define a worker. When leaving the action, suddenly the connection to backgroundrb is lost: DRb URI: druby://localhost:22222 Pid: 3976 Autostart... done druby://localhost:42531 - #<Errno::EBADF: Bad file descriptor -

Hi list, According to the libvirt documentation [1] "Show maximum number of virtual CPUs for guest domains on this connection" This may not be a complete definition. My first guess from the above was that this returns the number of virtual CPUs that can exist at the same time on the host, either one or several VMs. In fact it returned 16 in my fedora 20 desktop running with KVM,

Hi, I couldn't find a discussion that specifically addresses this, so here it is. I'm using Speex AEC in my mobile VoIP application to cancel speaker echo. The used version is 1.2rc1 from the website, and I'm compiling with fixed-point. On most occasions, the AEC works very well and cancels most of the echo (combined with the preprocessor). On some devices, where the microphone signal

Hi Hal, A pre-emit pass will indeed be preferable. I originally thought of it, too, however I could not figure out how can such a pass have an access to information on instruction sizes and block alignments. I know that for X86, at least, the branch relaxation is happening during the layout phase in the Assembler, where I plan to integrate the nop insertion such that the new MCPerfNopFragment

Hi Hal, Thanks for the reference. I’ve looked at PPCBranchSelector and the PowerPC backend. It is very different from the X86 architecture and unfortunately the way branch relaxation and alignment related issues are handled in PPC cannot be copied to X86. This is because: 1. PPC instructions are of fixed length while X86 instructions are of variable length, and their length can change

Hi Jean-Marc, thanks for the response. First, I will clarify again that floating-point solves this - so isn't that a bug in fixed-point? Also, I understand that algorithmically the AEC won't cancel echo properly on a non-linear signal, but why completely distort the output? If the echo just won't get cancelled it would be acceptable, but in the current state it disables the ability to

Is there a generic function that gives the machine instructions and their patterns given in the .td files of a backend specification ? or a subset which match a certain opcode ? otherwise how are the machine instructions being accessed/matched for instruction selection ? -Omer -------------- next part -------------- An HTML attachment was scrubbed...

Hi, i want to start domain with 2 cpus avail, but also have the opportunity to change on-the-fly the number of cpus to, for example, 4. in my domain.cfg i have: vcpus = 2 vcpu_avail = 7 The domain starts with 2 cpus, as expected, but rising the number does not work. It silently fails. Lowering the number works as expected. $ xm vcpu-set domain 3 $ xm list Name

Hi all, These days I am working on a feature designed to insert nops for IA code generation that will provide performance improvements and performance stability. This feature will not affect other architectures. It will, however, set up an infrastructure for other architectures to do the same, if ever needed. Here are some examples for cases in which nops can improve performance: 1. DSB

Hi, I am new to tc, please forgive me for simple question. I have linux 2.4 in my routers, I would like to use HTB. I have downloaded binary code from http://luxik.cdi.cz/~devik/qos/htb/#source, (tc.gz), but I could not open the file. Is there any other place I can get binary code for HTB. Also if you can give some direction how to patch it, it will be really helpful. Thanks in advance Omer

I've searched the Samba docs, man pages, Using Samba, and a few other places. I've been unable to find a way to retrieve the browse list (as in Network Neighborhood or net view on Win32) from Samba. I'm using a RH 6.2 box running Samba 2.0.7 in a multi-subnet workgroup (which is really a domain, but I don't have a machine trust account and I'm using security = server). Samba is

Hello, a probably rather stupid question to which I can't find an answer: I have a bar chart, and I want to present which bars are significantly different by placing a line with an asterisk above then (similarly to fig. 3 in: http://jnm.snmjournals.org/content/46/4/574.figures-only). Does anyone have a reference where can I find some instructions how to learn this? Thanks a lot! Omer --

Hey Ian and Stefano, Please see this thread: http://lists.xen.org/archives/html/xen-devel/2013-05/msg01053.html for the debug patches and some of the discussion. These three patches fix an race that has been in QEMU traditional for a long time. The guts of the bug is that if you have a guest with these options: vcpus=1 maxvcpus=32 and do ''xl vcpu-set <guest> 32'' the

My dom0 is uing Centos 5.2 x64. I have just upgraded Xen from 3.3.0 to 3.3.1. After upgraded, I find that I cannot hotplug additional vcpu anymore. I have a domU "linux1" which is a paravirtualized vm with centos 5.2. I try to "xm vcpu-set linux1 4", it does not have any error message, but those vcpu cannot be displayed. I also tried to add vcpu using "virsh setvcpus
