Hi Punit, Can you try to create another vm the same as this one, but without installing all these packages, see if it reproduces after some time. If not please provide a list of the packages you installed, maybe the problem is somewhere there. If it does reproduce please provide again the vdsm log and also the engine log. Another thing to check would be the connectivity to your storage, when this happened, the storage domain was up? can you try ping the storage server from the host if it happens again? What os is installed on your host? 10x. Sefi. ----- Original Message ----- From: "Punit Dambiwal" <hypunit(a)gmail.com&gt; To: users(a)ovirt.org, "Martin Pavlik" <mpavlik(a)redhat.com&gt;, "Kanagaraj" < kmayilsa(a)redhat.com&gt; Sent: Wednesday, January 28, 2015 5:58:27 AM Subject: [ovirt-users] Strange Issue after guest VM reboot | boot failed :- not a bootable disk Hi, I have created one vm in the ovirt successfully...it was working fine....i login to it and download some httpd packages etc....after 5-10 min...it stop receving the commands from SSH ...if nothing help then I power off the machine… then power on again.. then the VM display the error that "boot failed :- not a bootable disk" Even the disk is bootable...
