Hi there, I''ve read the paper on Xen live migration, and it shows some very impressive figures, like 165ms downtime on a running web server, and 50ms for a quake3 server. I installed CentOS 5 on 2 servers, each with 2x Xeon E5335 (quad-core), 2x Intel 80003ES2LAN Gb NICs. Then I installed 2 DomUs, also with CentOS 5. One NIC is connected to the LAN (on the same switch and VLAN), the

Hi there, I was looking for a GSM gateway, but I didn't find any prices... Anybody knows how much one of these costs? And, is it possible to use an amateur radio with asterisk? Thanks, Marconi.

I had this idea, and after looking for something like this already in progress, I found another guy who tried to start it... But I was unable to contact him, and his project seems to be dead. But, I believe it is possible, and I wanted to know the opinion of the experienced... So, let's go: I got an asterisk server setup to receive free calls from US to Brazil. The problem is that at my work,

Hi, How do I put a call on hold? If i press # the music on hold plays to the other person, but asterisk asks for a number to transfer... I don't want to transfer, I simply want to put the person on hold, so he/she can hear the music while I do something, then get them off hold. Is it possible? The scenario: The person calls me from a SIP phone, and I receive the call in a regular PSTN phone,

Hi there, I''ve noticed a strange behaviour: I have a windows 2003 vm using 4 vcpus. In xm top, it says the vm is using 399% cpu. But inside the win vm, I see only around 2% cpu use. Is that supposed to be that way? What is really happening? Are those physical cpus (cores) really being 100% used? If I have 8 cores, and I set 2 or 3 vms with 4 vcpus each, will that annihilate performance,

Hi there, It took me a while to find out that there were no xen-vncfb included in the binary x86_64 (don''t know about the other architectures) tarball, and that it was causing xm create to fail (obviously, when the domU had vfb defined). Is there a reason for this? Or they just forgot? Thanks, Marconi. _______________________________________________ Xen-users mailing list

Hello, Could anybody point me where to find the internal structures of the COW devices in /dev/mapper? What I want to do, exactly, is: make a backup of the snapshot in an image file, reading all the used blocks, and leaving the "not-used" ones. Later, I want to get the image file, and restore the cow device. But I can''t find an LVM document describing exactly how the COW

First, I am surprised at IAX... My asterisk server is behind a firewall, I am behind a firewall, and my iax client connected... Voodoo??? :) But, the firewall has one unblocked port, which I think I should set to the IAX, so the magic won't be necessary, and it makes sense to think that there will be less latency without the "magic layer". But, when I set port=myport in the

Hi there, I got really tired of false hangups, specially when someone calls from SIP/IAX/whatever to PSTN, which makes no sense in using busydetect in the zap channel, as the caller will eventually hear the busy tones and hangup, causing the zap channel to be "freed" as well... After suggesting that the busy detect be enabled only for inbound calls, and finding other people that think

Hi there, I've seen people using SER with Asterisk. I took a look at SER website, and I didn't see the point in using it, since Asterisk already handles SIP very well (apparently, at least). But, as I'm starting, and some of you (more experienced) use it, I know that there's something there... So I would like to know why to use SER. Is it because of scalability, performance,

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.

Two days ago, I was talking on the phone from the FXO, to a SIP phone. After some time (like 1h30m), all of a sudden, there's a huge noise, like a buzz... Really loud. So I hungup, and called my asterisk box again... All I could hear was that sound. Someone called me from the internet, and as Asterisk dialed the FXO, all she heard was that noise too. So, I logged in my Asterisk server,
