Hi Martin Here is some more info in the libvirt/qemu/instance...log file . Does it help in resolving the issue of : error : qemuMonitorIO:614 : internal>error End of file from monitor In the libvirtd.log file I sent you could see clearly that the debug option is active and this is the most detailed info available (or some better option than log_leve=1 exists ?) Thx Zvi Dubitzky

Hi For some reason recent libvirt code (0.8.3 and even before) the 'virsh shutdown <domain> ' is not effective . It issues an ok message but the domians remains in a runnning state . Only th e destroy works fine. Any idea ? thanks Zvi Dubitzky Email:dubi at il.ibm.com

Hi I was asking about the fedora 14 kernel if it is good enough for cgroup usage because I am trying to set a cgroup under cpu subsytem ( /dev/cgroup/cpu/group1/ ) that have /cpu.rt_runtime_us of 100000 while cpu.rt_period_us has a value of 1000000 i.e a ratio of 1/10 . still when I run a task (endless loop) in that group (cgexec -g cpu,cpuset:group1 ./test) it gets all the cpu core time

Using libvirt under openstack I encounter a problem when launching a VM with multiple partitions (2 G image) , While a single partition can be launched successfully . The launch is done with Openstack. We are using in libvirtd.conf log_level=1 and log_outputs="1:file:/var/log/libvirt/libvirtd.log" we can see that in /var/log/libvirt/libvirtd.log appear the following error

Hi Does Fedora release 14 (Laughlin) having Linux kernel 2.6.35.6-45.fc14.x86_64 support cgroup at the kernel ? thanks Zvi Dubitzky Email:dubi at il.ibm.com

My virtual machine xml file has <vcpu>2</vcpu> clause while the host has 2 physical cpus (cores). Is this enough to cause a VM running 2 endless loop threads to use the 2 cores ? In my case the VM running reports (cat /roc/cpuinfo) that it has 2 vcpus but it uses only 1 core (at a time) because the 'top' at the host shows 100%cpu (out of total 200%) used by the

I resolved topic 1 please diregard ( libvirtd.conf : Authentication / auth_tcp="none") .

Sorry, let me rephrase the question again: I need define a user /password for sasl but want the authentication at runtime be automatic - no explicit promting the user while accessing a tcp socket with some applications that need authentication (e.g libvirt) I try : saslpasswd2 -c -p -a libvirt <user> and it hangs (if i now press Enter it says : "invalid parameter

Hi we have a Debian 64 bit system with qemu 0.9.1-10 ( uname -a = 2.6.26-2-amd64) installed . kvm is included and loaded to memory . Still when we create a VM we sometimes get the following error message: libvir: QEMU error : internal error unable to start guest: You do not have enough space in '/dev/shm' for the 499 MB of QEMU virtual RAM. To have more space available provided you

libvirt schedinfo : ------------------ What is the meaning of the 'cap' parameter in the schedinfo virsh command (what are the units and range of values ) and what is the 'weigth' parameter ? Zvi Dubitzky Email:dubi at il.ibm.com

I have 2 VMs launched by : 'virsh create <xml file>' . Both VMs get 2 vcpus (out of total 2 cores of the host) I then try bias their cpu cycle quota by manipulating the cpu_shares ( virsh schedinfo --set cpu_shares=<value> vm1/2 ) so that VM1 will get 3 times the cpu cycles VM2 gets. (e.g : VM1 cpu_shares = 150 . VM2 cpu_shares = 50) . There are no other VMs defined or

I need define a user /password for sasl but want that to do the verification automatically no -promting ( or even maybe avoid the verification) while using a tcp socket with some applications that need authentication (e.g libvirt) so I try : saslpasswd2 -c -p -a libvirt <user> and it hangs (if i now press Enter it says : "invalid parameter supplied") . if I avoid

I have fedora14 installed with standard libvirt-0.8.3. I can start VM using .xml files and also run: virsh schedinfo. the cgroup CPU controller is mounted and active . In fact I have the path to the Virtual machine : /dev/cgroup/cpu/libvirt/qemu/<vm name > Now I upgraded to libvirt-0.8.8 from a tar ball ( configure , make , make install) . I rebooted , new libvirtd started . virsh

Hi Does anybody use the 'virsh memtune' command and can he say what combination of libvirt version and libcgroup does he use thanks Zvi Dubitzky Email:dubi at il.ibm.com

We use InstCombiner::ShouldChangeType() to prevent transforms to illegal integer types, but I'm not sure how that would apply to vector types. Ie, let's say v256 is a legal type in your example. DataLayout doesn't appear to specify what configurations of a 256-bit vector are legal, so I don't think we can currently use that to say v2i128 should be treated differently than v16i16.

Right - I think that case looks like this for little endian: define <2 x i32> @zextshuffle(<2 x i16> %x) { %zext_shuffle = shufflevector <2 x i16> %x, <2 x i16> zeroinitializer, <4 x i32> <i32 0, i32 2, i32 1, i32 2> %bc = bitcast <4 x i16> %zext_shuffle to <2 x i32> ret <2 x i32> %bc } define <2 x i32> @zextvec(<2 x i16>

Thanks, Sanjay, that makes sense. The opportunity for improving instcombining splat sounds promising. Another question about shuffle simplification. This is a testcase from test/Transforms/InstCombine/vec_shuffle.ll: define <4 x i32> @test10(<4 x i32> %tmp5) nounwind { %tmp6 = shufflevector <4 x i32> %tmp5, <4 x i32> undef, <4 x i32> <i32 1, i32 undef, i32

Hi, Zvi, I agree. In the context of targeting the KNL, however, I'm a bit concerned about the addressing, and specifically, the size of the resulting encoding: > vmovdqu32 zmm0, zmmword ptr [rax + c+401280] ;load b[401280] in > zmm0 > > vpaddd zmm1, zmm1, zmmword ptr [rax + b+401344] > ; zmm1<-zmm1+b[401344] The KNL can only
