Hi All, finally, I've got time and resources for development. Unfortunately I couldn't afford playing with my UPS because it was used permanently, but now it's ok. I've checked out cureent trunc and I see that Andrey Lelikov's changes haven't been applied yet. What's wrong with them? I think, he made a great job to simplify future support for this kind of

Hi. Consider the following situation: Solaris 8, /usr/local has gcc 2.95, my home has gcc 3.4.3, my gcc is first on PATH, LD_LIBRARY_PATH is unset (everything is perfect since I always use -R). In fact, programs compiled with my gcc do not work if LD_LIBRARY_PATH is set to something which has /usr/local/lib before home/lib, because it overrides stored path (-R) and I got libgcc_s.so.1

Hi all, I have a question about NFS datastore and unsafe migration. When migrating a virtual machine having a virtio disk in writeback cache between two hosts sharing a single NFS datastore, I get the following error: "Unsafe migration: Migration may lead to data corruption if disks use cache != none or cache != directsync" I understand why libvirt alerts for unsafe migration in

Greetings Has libvirt dedicated page cache area for guest ? If not - what is the difference between cache='none' and cache='directsync' ? >The optional cache attribute controls the cache mechanism, possible >values are "default", "none", "writethrough", "writeback", "directsync" >(like "writethrough", but it

There is a problem when importing an spss-file containing explicitly declared missing values in R using the read.spss function from the foreign package. I'm not sure these problems are the same in every version of spss, I am using the latest version 16.0.2. I included http://www.nabble.com/file/p18776776/missingdata.sav missingdata.sav and

Hi, When an audiopacket is received too late I could interpolate this frame. The problem is that I don't know if it is a true bufferloss or just the last audiopacket of a talkspurt. Now my question is if it's harmfull for the audioquality that at the end of the talkspurt one frame is interpolated? Or would this be almost inpossible to hear since the last audiopacket in the talkspurt

Hi all, I write about libvirt inconsistent behavior when mixing io=native and cache=writeback. This post can be regarded as an extension, or clarification request, of BZ 1086704 (https://bugzilla.redhat.com/show_bug.cgi?id=1086704) On a fully upgraded CentOS6 x86-64 machine, starting a guest with io=native and cache=writeback is permitted: no errors are raised and the VM (qemu, really)

Hi There, I've moved some Windows2012 with MSSQL VMs from an hold ESXi 5.5 machine to a more recent and powerful machine running Fedora 24 x86_64 and related libvirt + KVM virtualization. I've moved the VMs filesystem to LVM slices and installed the VirtIO drivers in to all Windows VMs. I've also set both Disk and Network interface to work using VirtIO. So far so good everything works

Hi all, I'm using Samba (AD) under Debian Buster. Testparm tells me the idmap of TDB and AD would overlap. However the configured range don't.

I think I share the goal with you to make the foundation for better dead-strip, so thank you for suggesting. I'm not sure if marking a section as a whole as "safe" or "unsafe" is the best approach, though. Some comments. - If the compiler generated code is always "safe", and if we can distinguish it from hand-written assembly code by checking if there's a

Then how about enable these flags for -O2? I want to hear from other people cc'ed, and I may be too cautious, but I'd hesitate to define a new ELF section if there's other mean already available to achieve the same thing.

I'm running libvirt 0.10.2 and qemu-kvm-1.2.0, both compiled from source, on CentOS 6. I've got a working blkio cgroup hierarchy which I'm attaching guests to using the following XML guest configs: VM1 (foreground): <cputune> <shares>2048</shares> </cputune> <blkiotune> <weight>1000</weight> </blkiotune>

Is there any reason -ffunction-sections and -fdata-sections wouldn't work? If it'll work, it may be be better to say "if you want to get a better linker output use these options", rather than defining new ELF section.

Not all users compile their code with -ffunction-sections and -fdata-sections. This is to handle usecases when libraries use a mix of object files too.

Hi, libvirt (0.9.11) refuses to start KVM based virtual machines on my system when changing the network connection from "host bridge" to "direct" (macvtap/macvlan), neither in "bridge" nor in "vepa" mode: "Cannot create macvlan devices on this platform" That's astonishing because I can easily setup working macvlan devices using the

Hi, it is possible to define a domain along with several usb host controllers, e.g. <controller type='usb' index='0' model='ich9-ehci' /> <controller type='usb' index='1' model='ich9-uhci' /> How to distinguish between those controllers/busses when adding input or host devices such as <input type='tablet'

Hi All, I've been chasing down an issue in recent weeks (my own lab, so no prod here) and I'm reaching out in case someone might have some guidance to share. I'm running fairly large VMs (RHOSP underclouds - 8vcpu, 32gb ram, about 200gb single disk as a growable qcow2) on some RHEL7.6 hypervisors (kernel 3.10.0-927.2x.y, libvirt 4.5.0, qemu-kvm-1.5.3) on top of SSD/NVMe drives
