Problem with libvirt migration
I have two hosts, vm1 and vm2, which are both running libvirt 0.7.0. They share a common ocfs2 file system that resides on a san, and have identical network configurations. I am running qemu-kvm 0.11.0 on ubuntu 9.10 servers. I start base32 on vm1 and it comes up (it also runs fine if started on vm2). Then from vm2 I do: vm2#: virsh -c qemu://vm1/system migrate --live base32 qemu://vm2/system

Hard lock with 4.14.0-2
I am running Debian testing and updated my system this morning which included a new kernel: 4.14.0.2-amd64 After this update, my system froze twice -- both times the exact same behavior. In both situations, the system froze while I was resizing a window. The mouse cursor froze, clock stopped, num lock stopped working. I didn't check if the system responded to pings from a remote machine,

create vm timeout
Hi all: I create VM on most hypervisors very quickly, about 2 seconds. But some hypervisors are slow, taking more than 10 seconds. I started the debug log for libvirtd and found that some threads had timed out. Thread 95205 has two 5-second timeouts, but I don't know why? Below some information about my hypervisor: [root@node1 datapool]# virsh -v 3.4.0 [root@node1 datapool]# qemu-x86_64

r-base installation fails on Ubuntu 14.04
Possibly off the wall and a long shot, but is pre-installed Linux perhaps 32 bit, while the R attempt is 64?

r-base installation fails on Ubuntu 14.04
I can make a few suggestions to help you hunt for the issue. This kind of error is often caused by conflicting packages from proposed, backports, ppas, or other 3rd party repos. If for some reason you have a dependency installed from one of those sources that is newer than what R on cran was built against (stock ubuntu 14.04) then you will hit a conflict. Simply removing backports from your repos

r-base installation fails on Ubuntu 14.04
That could do it http://packages.ubuntu.com/trusty-backports/libcgmanager0 Seems to be libc related, which is a pretty core library to much of the whole system. Hmm, which model Dell? We just got a Dell 5000 series with Ubuntu, I have not checked with my boss if there was R installation issues.

Synaptic can show the origin of packages. The only thing I see from a backport is libcmanager0 I don't think this is relevant to R. Or is it. The only thing I've got installed from a ppa is mate (a desktop). I don't see anything related to mate that is related to R. FYI the ubunu I'm using came preinstalled from Dell (on a notebook; usually I install linux myself). On

r-base installation fails on Ubuntu 14.04
It's a Dell XPS 13. Obviously I don't understand what's in libcmanager0. I wonder if I can safely replace it. I'm a bit uneasy about replacing things Dell installed. I gather there are some specialized drivers for the monitor on this system. On 03/23/2016 11:34 AM, Alex M wrote: > That could do it > http://packages.ubuntu.com/trusty-backports/libcgmanager0 > >

Upgrading from Debian Stretch to Buster, Van Belle package
Ah, ok, apt-get remove libldb1 ldb-tools Then try again : apt install samba winbind acl The replacement of libldb1 to libldb2 is missing something. I'll have a look at that.

ActiveRecord & Prepared Statement
I searched the archives and found a thread about it, but I didn''t understand: are prepared statement used by ActiveRecord on those databases that could handle them (Postgresql, Mysql, Oracle etc)? In case they are not used, are they planned? Is there a roadmap about Rails I can find somewhere?
