I tried debugging this ..I put a lot of debug messages and I found that the problem lies in the libxkutil/device_parsing.c cleanup_dominfo() function It faults when we try to *"free(dom->os_info.pv.initrd); " . *The struct domain does not seem to have initrd property see below: ============ struct domain { enum { DOMAIN_XENPV, DOMAIN_XENFV, DOMAIN_KVM, DOMAIN_QEMU, DOMAIN_LXC } type; char *name; char *typestr; /*xen, kvm, etc */ char *uuid; char *bootloader; char *bootloader_args; char *clock; union { struct pv_os_info pv; struct fv_os_info fv; struct lxc_os_info lxc; } os_info; int on_poweroff; int on_reboot; int on_crash; struct virt_device *dev_graphics; int dev_graphics_ct; struct virt_device *dev_emu; struct virt_device *dev_input; int dev_input_ct; struct virt_device *dev_mem; int dev_mem_ct; struct virt_device *dev_net; int dev_net_ct; struct virt_device *dev_disk; int dev_disk_ct; struct virt_device *dev_vcpu; int dev_vcpu_ct; }; I commented out the part of code "free*(dom->os_info.pv.initrd)" and the test case passed. * -- Thanks and Regards, Deepti B.
