<p class=MsoNormal><resending as I don’t think I was in the mailing
list yet when I sent first time… apologies if you receive this twice><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal>I’m facing some strange behavior, and I hope you can
provide a clarification. <o:p></o:p></p>
<p class=MsoNormal>Consider the following code:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
virDomainPtr dom = virDomainLookupByName(virt, domain_name);<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
if (dom) {<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
printf("domain already defined...\n");<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
if (virDomainUndefine(dom))<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
printf("...unable to undefine!!!\n");<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
else {<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
printf("...undefined.");<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
free(dom);<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
}<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
}<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
dom = virDomainDefineXML(virt, SOME_XML);<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
if (dom != NULL) {<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
const char *name = virDomainGetName(dom);<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
printf("NAME IS NOW: %s\n", name);<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
} else<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Courier New"'>
printf("dom is NULL!\n");<o:p></o:p></span></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When executed the first time, the code correctly defines the
domain, and prints:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-family:"Courier New"'>defining
domain test2-vm<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-family:"Courier New"'>libvir:
QEMU error : Domain not found: no domain with matching name 'test2-vm'<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-family:"Courier New"'>NAME
IS NOW: test2-vm</span><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If executed a second time with the same SOME_XML when
the domain is already defined, it prints:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-family:"Courier New"'>defining
domain test2-vm<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-family:"Courier New"'>domain
already defined...<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-family:"Courier New"'>libvir:
Domain error : invalid domain pointer in virDomainGetName<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='font-family:"Courier New"'>undefining......undefined.NAME
IS NOW: (null)<o:p></o:p></span></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Not only the name is null, but the domain can’t be
started. What is the correct way to undefined programmatically a domain that is
already defined? Why is the second virDomainDefineXML() returining a pointer
(as opposed to null), but the pointed object seem to be invalid?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks, <o:p></o:p></p>
<p class=MsoNormal>
