similar to: Problem using virt-manager to create a VM remotely

Hi all, I've succeed to do live migration between two PCs. However, I found I could not connect the VM by host IP from a remote PC before migration and can only connect it from host PC. If I appended the VM with the following line at the end of the xml file: <listen type='address' address=host_IP port='PORT'> I can connect the VM via VNCVIEWER with host_IP:PORT.

Hello, I was getting the following error in syslog: libvirtd: 21:19:12.116: 10955: error : qemudDispatchServer:1355 : Too many active clients (20), dropping connection from 127.0.0.1;0 I investigated a bit and tried the following in a python console: import libvirt ~~~~ conn=libvirt.openReadOnly("qemu+ssh://HOST_IP/system<http://10.16.71.1/system> ") //now check the no. of

I am running Xen on a RHEL4 dom0 and have two RHEL4 domU''s. The domU''s are both running Oracle 10g R2 database. I want to connect to these databases from another computer. Xen is set up with NAT network and all dom''s have access to the internet and they can ping eachother so the network is up and running. My problem is that I cannot connect to the different oracle

Just in case anyone is using Blockhosts (http://www.aczoom.com/blockhosts/) with their Linux servers and Asterisk here are the rules necessary to block invalid users: "asterisk-NoPeer": r'Registration from .* failed for \'{HOST_IP}\' - No matching peer found', "asterisk-NoAuth": r'Registration from .* failed for \'{HOST_IP}\' - Username/auth name

Hello everybody! Currently, dovecot just kills itself if it detects that time has moved backwards more than a hardcoded number of seconds. I accept the reasons, but I do not like to restart dovecot manually after waiting for time to move forward again. A cron job would not help, because time might still be wrong when it restarts dovecot. All our systems run ntpd, but they might be offline

Hi list, I have a problem with Mongrel which is really bugging me. I would really appreciate any help that anyone can provide to help me in solving this problem. 1. My setup: Apache front_end with mod_proxy_balancer in front of 4 mongrel/rails instances of my application. Rails 1.2.5 Ruby 1.8.6 Mongrel 1.1.1 2. I noticed that the CPU consumption on my server was 100% being consumed by ruby so I

Hi all! I have tried the imap_acl plugin with 1.2.9 today, but was not able to limit acl changes for those mailboxes where acl changes should be forbidden. http://wiki.dovecot.org/ACL says that "a" or "admin" covers "Administration rights to the mailbox". However, removing "a" from owner acl (using "lr") does not help, the user can still

Hi I have a rather strange problem with mongrel and I would be grateful if anyone could assist me with resolving. I have an application running mongrel 1.1.1 and rails 1.2.5 with ruby 1.8.6. It was all working fine and starting as expected. But I did a server reboot once and mongrel has refused to start up since. I get the following error:

I've a particular situation in which I need to sometimes delete one or two files from a remote site. I haven't figured out a way to do it with rsync yet... I've considered playing games with --exclude and --delete but I'm a bit nervous of the chances of mayhem by a simple error. Situation is a remote repository to which files are added on occasion; there is no local copy. On

Hi folks, first of all thanks for Dovecot, I appreciate it a lot. On one of our servers, we experience regular tries to brute force logins, probably based on harvested mail addresses. Now I wonder if dovecot has or could in future have some mechanism to blacklist remote IP addresses after a configurable number of failures to login to any account. Blacklisted IPs could simply be disconnected

Hi all, I am interested in building a stand alone Rice Encoder/Decoder, using FLAC source code as a starting point. I've read the theory behind it, and I am very interested in info theory. However, I am struggling with how exactly I would implement the theory in code. I'm a newbie to computer science (only 1 year experience). I have read the format and documentation links on the FLAC

This may not be the best forum to ask, but it does seem to be one where it is as likely as anywhere that someone will have dealt with a similar problem. I need to define a procedure for last resort disaster recovery from an incremental file level backup of the root partition (and any others that are critical.) Now it is easy enough to create a raw virtual disk with dd, then to losetup and do a

Hi All it is possible to tune dom0/domU for better IO/network performance? Since I have changed to Cenots7 dom0, I have a really poor IO performance inside a PV VM. I have already done what is described on http://wiki.xenproject.org/wiki/Tuning_Xen_for_Performance It is better now but still significantly worse than with centos6 dom0 my settings: xen parameter: dom0_mem=1024M cpufreq=xen

I have shifted some VM's to a new server running Quantal and have had a world of trouble. The first one was caused by issues with an apparently compiled in path in their apparmor version which forced VM pools to be in /srv or similar rather than where I wanted them. For now this was not a big issue, and thankfully the server where it would be a big time problem (there are individual drives per

This patch adds support for the new virtio-mmio transport layer added in 3.2-rc1. The purpose of this new layer is to allow virtio to work on systems which don't necessarily support PCI, such as embedded systems. To apply the patch on top of the KVM tools tree, you must first pull Linus' tree on top. Also, CONFIG_VIRTIO_MMIO=y should be set in the guest kernel. This is an early RFC,
