Package: xen-hypervisor-4.6-amd64
Version: 4.6.0-1
Severity: normal
Dear maintaners,
I was using XEN 4.4 on that machine ("unstable") and want to switch to 4.6.
All xen stuff was uninstalled (XEN 4.4), the machine restarted before
installing 4.6. When I uninstall XEN 4.4 (libxenlight4.4) it deinstall also
part of QEMU and when I reinstall QEMU libxenlight-4.4 aws reinstalled.
First try (noeload is the file descripting the VM, was OK with xen4.4, the file
is enclosed):
xl create neoload
/usr/lib/xen-4.6/bin/xl: error while loading shared libraries:
libxenlight-4.6.so: cannot open shared object file: No such file or directory
The "/usr/lib/xen-4.6/lib" contains only :
/usr/lib/xen-4.6/lib
total 64

Where is "libxenlight" ?
cd /usr
find ./ -name 'libxenlight*'
./lib/x86_64-linux-gnu/libxenlight-4.4.so
Only the libxenlight-4.4 is present ? There is a dependency whith "qemu" so it
was reinstalled with qemu.
I try to reinstall libxen-4.6 (4.6.0.1 was marked as installed) a and
cd /usr
find ./ -name 'libxenlight*'
./lib/x86_64-linux-gnu/libxenlight-4.6.so
./lib/x86_64-linux-gnu/libxenlight-4.4.so
give another try :
xl create neoload
Parsing config from neoload
After many minutes nothing happens so I try to give up with Ctrl+c ... without
any success. Can't kill the xl process even with kill -9.
Libvirt was not ok (searching libxenlight-4.6, and can't alse been restarted or
even killed, so I restart the system and get some "oops" while stopping (10
minutes to stop with systemd!!!).

After restarting the system :
libvirtd seems to be OK (no messages in log)
Xen processes seems to bo OK :
ps -ef | grep xen
root 49 2 0 16:00 ? 00:00:00 [xenwatch]
root 50 2 0 16:00 ? 00:00:00 [xenbus]
root 57 2 0 16:00 ? 00:00:00 [xenbus_frontend]

root 3191 1 0 16:00 ? 00:00:00
/usr/lib/xen-4.6/bin/xenconsoled --pid-file=/var/run/xenconsoled.pid
So I try :
xl create neoload
Parsing config from neoload
xc: error: Could not open kernel image '/usr/lib/xen/boot/hvmloader' (2 = No

libxl: error: libxl.c:1549:domain_destroy_callback: unable to destroy guest

libxl: error: libxl.c:1476:domain_destroy_cb: destruction of domain 1 failed
The directory "/usr/lib/xen" does not exist on my system ! And no "hvmloader"
program as in previous versions.
The /usr/lib/xen-4.6 directory does not even contain a "boot" subdirectory, so
I don't try to install a symlink.
