Description of problem: If there isn't enough memory for the guest kickstart to proceed it fails on the client. But the UI thinks its still in progress. The issue here is that the right error code is not communicated to the server so the kickstart action can be shown as a failed instead of in progress. Even though a libvirtError('virDomainCreateLinux() failed', conn=self) is raised, the action is still show as being scheduled successfully. See tracback followed by the response sent to the server. How reproducible: always Steps to Reproduce: 1. schedule a guest kickstart for RHEL5-x86_64 2. rhn_check -vvvv $ rhn_check -vvvv D: do_call kickstart_guest.initiate ('rlx-0-16.rhndev.redhat.com', 'rlx-2-22.rhndev.redhat.com:1:RHEL5-x64', 'xenpv', 65, 'RHEL5-x64', 524288, 1, 5, 'xenbr0', '/var/lib/xen/RHEL5-x64', 'ks=http://rlx-0-16.rhndev.redhat.com/ty/LakMzDQV ksdevice=eth0 ') - looking for Cobbler at http://rlx-0-16.rhndev.redhat.com/cobbler_api - reading URL: http://rlx-0-16.rhndev.redhat.com/cblr/svc/op/ks/system/rlx-2-22.rhndev.redhat.com:1:RHEL5-x64 install_tree: http://rlx-0-16.rhndev.redhat.com:80/ty/nzfHPtpZ libvirtd (pid 1942) is running... downloading initrd initrd.img to /var/lib/xen/initrd.img url=http://rlx-0-16.rhndev.redhat.com/cobbler/images/ks-rhel-x86_64-server-5-u3:xen/initrd.img - reading URL: http://rlx-0-16.rhndev.redhat.com/cobbler/images/ks-rhel-x86_64-server-5-u3:xen/initrd.img downloading kernel vmlinuz to /var/lib/xen/vmlinuz url=http://rlx-0-16.rhndev.redhat.com/cobbler/images/ks-rhel-x86_64-server-5-u3:xen/vmlinuz - reading URL: http://rlx-0-16.rhndev.redhat.com/cobbler/images/ks-rhel-x86_64-server-5-u3:xen/vmlinuz libvir: Xen error : Domain not found: xenUnifiedDomainLookupByUUID libvir: Xen error : Domain not found: xenUnifiedDomainLookupByName libvir: Xen Daemon error : POST operation failed: (xend.err 'Error creating domain: (4, \'Out of memory\', "xc_dom_boot_mem_init: can\'t allocate low memory for domain\\n")') libvirt.libvirtError virDomainCreateLinux() failed POST operation failed: (xend.err 'Error creating domain: (4, \'Out of memory\', "xc_dom_boot_mem_init: can\'t allocate low memory for domain\\n")') File "/usr/share/rhn/spacewalkkoan/spacewalkkoan.py", line 116, in initiate_guest k.run() File "/usr/lib/python2.4/site-packages/koan/app.py", line 296, in run self.virt() File "/usr/lib/python2.4/site-packages/koan/app.py", line 584, in virt return self.net_install(after_download) File "/usr/lib/python2.4/site-packages/koan/app.py", line 503, in net_install after_download(self, profile_data) File "/usr/lib/python2.4/site-packages/koan/app.py", line 582, in after_download self.virt_net_install(profile_data) File "/usr/lib/python2.4/site-packages/koan/app.py", line 1051, in virt_net_install virt_type = self.virt_type File "/usr/lib/python2.4/site-packages/koan/xencreate.py", line 177, in start_install guest.start_install() File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 822, in start_install return self._do_install(consolecb, meter, wait) File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 843, in _do_install self.domain = self.conn.createLinux(install_xml, 0) File "/usr/lib/python2.4/site-packages/libvirt.py", line 573, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) D: Sending back response (0, 'Guest kickstart initiated successfully.', {}) D: do_call packages.checkNeedUpdate ('rhnsd=1',) D: Called refresh_rpmlist Updating package profile D: local action status: (0, 'rpmlist refreshed', {}) D: closed db index /var/lib/rpm/Providename D: closed db index /var/lib/rpm/Packages D: closed db environment /var/lib/rpm/Packages D: May free Score board((nil)) 3.
