[libvirt-users] libvirt hang on domain attemp to create domain
good day, i am trying to create domain via virDomainDefineXML. and my program
hanging, also i failed to caonnect to libvirt daemon with virt-manager after
this, only killing libvirtd via SIGKILL and restarting it solveing hang (i
mean after restart i able to connect with virt-manager), i using following
domain xml
<?xml version="1.0" encoding="UTF-8"?>
<domain type="kvm">
<tittle>Automatically created domain with default
configuration</tittle>
<name>vm1</name>
<description>no description</description>
<os>
<type>hvm</type>
<boot dev="cdrom"/>
<boot dev="hd"/>
</os>
<vcpu>1</vcpu>
<memory unit="MB">512</memory>
<cpu model="host-model">
<topology sockets="1" cores="1"
threads="1"/>
</cpu>
<clock offset="localtime"/>
<devices>
<graphics type="vnc" autoport="yes"
password="admin"/>
<channel type="unix">
<source mode="bind" path="/var/run/vm1.sock"/>
<target type="virtio" name="org.guest_agent.0"/>
</channel>
</devices>
</domain>
i have this calls on stack
0 0x00007ffff48c1750 __poll_nocancel
1 0x00007ffff649e5ca virNetClientIOEventLoop
2 0x00007ffff649ed96 virNetClientSendInternal
3 0x00007ffff64a0443 virNetClientSendWithReply
4 0x00007ffff64a0daa virNetClientProgramCall
5 0x00007ffff6478566 callFull.isra.2
6 0x00007ffff6487fa2 remoteDomainDefineXML
7 0x00007ffff6449d2f virDomainDefineXML
8 0x0000000000426941 virt_domain::create

9 0x000000000040c1a9 main

Are you able to get libvirtd debug logs so we can see what's going on? http://wiki.libvirt.org/page/DebugLogs BTW, what's the libvirt version you are running?
