Hi,
I'm trying to do Auto Core Dump with compress file format for
dump_image_format (such as: bzip2) on Fedora Core 20, but the generated
dump image format is not "bzip2".
Here are my steps:
1. Prepare a running guest with following configuration in guest's xml
# virsh dumpxml domU
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
<on_crash>coredump-destroy</on_crash>
<qemu:commandline>
<qemu:arg value='-device'/>
<qemu:arg value='pvpanic'/>
</qemu:commandline>
</domain>
2. Set following values in /etc/libvirt/qemu.conf
dump_image_format = "bzip2"
auto_dump_path = "/var/lib/libvirt/qemu/dump"
3. Restart libvirtd service
4. Crash the guest os with the following command in guest
#sync
#echo c >/proc/sysrq-trigger
5. Check the core dump file under "/var/lib/libvirt/qemu/dump" with
file command
The output for file command is: (not bzip2 compress format)
#file coreDumpFile
ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style
So, I want to confirm whether compress file format for dump_image_format
is supported by Auto Core Dump?
Thanks.
