Take the Snapshot of the Virtual Machine which is hung or unresponsive state. When the Guest OS is Hung or unresponsive, Login to the vCenter Server or ESXi host using vSphere Client or vSphere Web ClientĢ. The vmss2core tool can produce core dump files for the Windows debugger (WinDbg), Red Hat crash compatible core files, a physical memory view suitable for the Gnu debugger gdb, Solaris MDB (XXX), and Mac OS X formats.īelow is the procedure to generate the crash dump or core dump of VMware Guestsġ.
It can handle both suspend (.vmss) and snapshot (.vmsn) checkpoint state files. Vmss2core is a tool to convert VMware checkpoint state files into formats that third party debugger tools understand. To better identify the route of this issue, We can generate the Crash dump using free tool from VMware Fling called Vmss2core. We will be just left with reboot option when we come across this type of issues in virtual machine. It’s been a real tough to identify the route cause of virtual machine become unresponsive or hung issues. It is real important to identify and provide the justification and Route Cause analysis for the downtime of critical applications is one of the important tasks of systems administrators. with the latest technology, lots of organization moved entirely into virtualization and highly critical workloads are running in Virtual machines. Advanced Hardware and hardware monitoring tools have the capability to send alerts in-case server become unresponsive due to hardware faults or parts failure. Server Hung or unresponsive become common issues in system administration. Diff VCenter 5.5 appliance and vCenter on WIndows.
