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 drwxr-xr-x 4 root root 4096 nov. 25 14:45 . drwxr-xr-x 4 root root 4096 nov. 25 14:45 .. drwxr-xr-x 9 root root 4096 nov. 25 14:45 fs -rw-r--r-- 1 root root 14592 nov. 1 21:58 libfsimage.so -rw-r--r-- 1 root root 31160 nov. 1 21:58 libxenstat.so drwxr-xr-x 4 root root 4096 nov. 25 14:45 python 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!!!).
