Re: [libvirt-users] Preloading shared library with libVirt

Hi, I am trying to preload two shared libraries while running Qemu using libvirt. To preload the shared libraries I have added an environment variable in the $domain.xml file with the following command: ``` virt-xml generic --edit --confirm --qemu-commandline 'env=LD_PRELOAD=/home/probir/Downloads/kpv_temp/temp/kvmTest/build_kvm/libperform.so:/home/probir/Downloads/kpv_temp/temp/kvmTest/dependencies/libmonitor/installDir/lib/libmonitor.so' ``` However, while running the domain, I get the following message of failure to preload the shared files in the log. ``` 2019-07-17 17:35:22.939+0000: starting up libvirt version: 1.3.1, package: 1ubuntu10.27 (Marc Deslauriers <marc.deslauriers(a)ubuntu.com&gt; Tue, 02 Jul 2019 09:22:37 -0400), qemu version: 2.5.0 (Debian 1:2.5+dfsg-5ubuntu10.39), hostname: probir-XPS-13-9343 LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin QEMU_AUDIO_DRV=spice LD_PRELOAD=/home/probir/Downloads/kpv_temp/temp/kvmTest/build_kvm/libperform.so:/home/probir/Downloads/kpv_temp/temp/kvmTest/dependencies/libmonitor/installDir/lib/libmonitor.so /usr/bin/kvm-spice -name generic -S -machine
