similar to: Cannot save/migrate domains

Hi, I am trying to migrate a domain (testDomain) from node1 to node2. Here is some information about the problem: node1#: xm migrate testDomain node2 After the command is executed, there is some communication between the node1 and node2 Xen hosts. xfrd daemon (which is forked by xend) is primarily responsible for vm migration and there is error in its log (/var/log/xfrd.log) The exact

Hi all, I want to do live migration of domains using DRBD block devices for synchronisation between the two Xen hosts with Xen 2.0.7. I''ve written a script ( block-drbd ) which binds / unbinds DRBD devices for specific domains (with DRBD, only one host can write on a drbd device at the same time). This script sets the current host as master (bind) or secondary (unbind) in a DRBD

Hello, I am trying to see if the hypervisor can be used to detect deadlocks in the guest VMs. My goal is to detect if a guest OS is deadlocked, and if it is, then create a clone of the deadlocked OS without the locking condition, and letting the clone run. While the clone runs I am hoping to generate some hints that could tell me what caused the deadlock. I simulated a deadlock/hang

Hi, I''m using xen on two-node redhat cluster (CVS devel version), using lvm as storage backend. redhat cluster is used to synchronize LVM metadata (using clvmd) and as storage for domain configs and dom-U kernels (with gfs). Latest version of redhat cluster works with xen-2.0.4, but not with xen-2.0-testing. ccsd failed to start on 2.0-testing. Anyone knows what the problem is? I

Hi, I'm new to NSD and would really appreciate if someone can point me to the right direction. I have like 8 NSD servers (secondary) serving around 30,000 zones. Zone updates are transferred from the primary DNS servers by AXFR/IXFR. The 8 NSD servers do not save the zones file on disk but are only held in memory. Therefore after NSD service is restarted zone transfer requests are being

Hi, I tried to issue: xm save VMID FILE, and got the following error: Error: Error: [Failure instance: Traceback: twisted.internet.error.ConnectionRefusedError, Connection was refused by other side: 111: Connection refused. xm create works fine, xend is running on domain 0, I can log in the VM through xm console VMID and ssh without problems. I can also stop and restart the domain.

Hi list, We are observing strange behavior of nsd v3.2.9 acting as slave DNS server. The environment is set up as follows: 0. We are using 172.16.0.0/16 subnet; 1. Primary Master server at 172.16.100.114; 2. Slave server at 172.16.100.115. The config file is in /etc/nsd-dns-slave.conf; 3. There may be also other Master servers im the given subnet. Now I want to permit DNS NOTIFY messages to

Hi all, I''ve been trying to figure out a way to trigger the balloon driver for a domain from within xfrd (specifically, libxc). So far, it doesn''t look like there''s a straightforward way. Is this even possible given the current structure of the system? Thanks, -A. -- Aaron Marks ajmarks@cis.upenn.edu Distributed Systems Lab University of Pennsylvania

Hi Jean Claude, The message is printed when the bind operation failed. Why that happens is hard to say, I'd need more information for that. As the message does not say: address already in use (or similar), I'm guessing the address is not configured?

I rebooted xenU from console (dom2) and exited (ctr-]). xm list does not report 2 anymore yet I can log into 2 via console and it is running just fine. Is this a bug? I''ll pull/rebuild and see what happens..

Last year we had a discussion[1] about how the hypercall ABI unfortunately contains fields that change width between 32- and 64-bit builds. This is a huge problem as we come up on the python management stack for ppc64, since the distributions ship 32-bit python. A 32-bit python/libxc cannot currently manage a 64-bit hypervisor. I had a patch but was unable to test it, and some other things were

Hi Andreas, The suggestions I captured in GitHub issues. Thanks for sharing. Regarding whether notifies are still plain UDP. Yes, the config parser doesn't accept additional arguments to "notify" and judging by the xfrd code anything to do with notify is using UDP, so no TLS yet. I've added a GitHub issue for this too. Thanks for the suggestions. They make for nice

Hi everyone! Does anyone use, rsync, under windows, without Cygwin?

Hello, It seems our NSD secondary has triggered some sort of intermittent bug After several weeks/months of running nsd stops forking with the new zone data. A manual nsd-control transfer or even nsd-control force_transfer won?t work, only restart of nsd solves the problem. The only ?hint? I?ve found is that the nsd xfrd messages stops appearing in the logs (while the notify messages keeps
