SEMI OT: Where to get SIP phones?
Looking back at an old email I sent to this list, around 5 years ago, I was commenting about a device for connecting a POTS phone to a USB port. Someone commented that it was a waste of money because you could buy SIP phones for under 300 NIS and posted a link. That link is long dead. The cheapest I could find were listed on Zap for 600 NIS. I was wondering if anyone knows of a source of SIP phones in Israel, preferably cheap. While expensive, fancy phones would be nice for business, cheaper ones, for home or small office use would be more of what I want. DECT or WiFi phones, would be good too. What does Orange give it's VoIP customers? Is that a SIP phone, or is just a DECT phone connected to their SIP router (OBOX)? BTW, if anyone has an old or used SIP or CISCO phones they would like to find a home for, I would appreicate them, and possibly can pay a little money for them.

Re: better platform for virtualization
PV drivers were released by Oracle, who run their own virtualization platform based on XenCommunity. KVM is wasteful and requires VT support even for Linux machines. Not only that, but its virtualized hardware is legacy old hardware supplied by QEMU. The leading virtualization solutions currently in the market are Vmware ESXi, which, for a single server is free and very nice (although you better make sure your hardware is in their support matrix), Microsoft Hyper-V, which is not Linux-friendly, if you care about it, and Citrix XenServer. You can compare these three on the internet. Less common, but aggressively in use (with the same performance profile) are OracleVM, RHEL Xen platform (with Oracle PV drivers for Windows) - Xen Community based. On the level of the low performance you would find Vmware Server, and Sun VirtualBox. KVM was designed, and is focused on VDI - desktop virtualization, being the focus of Kumranet in the past. RedHat cannot maintain two virtualization platforms. Assuming you aim at Windows virtualization, and assuming you want the assurance of enterprise-class solution, I would recommend any of the top three, with my favorite Citrix XenServer (check the pros and cons of each and make your own decisions in that matter). Other solutions are not complete, or will have near-zero support or knowledge base on the net. To make things clear - I earn my keep by performing various system and IT architecture-related integration operations, amongst are virtualization design and implementations. I have several customers with large XenServer farms, running mission-critical, 24/7/365. The longer one has his farm running since about March, containing about 40-50 VMs, including the company's Exchange server (~400 users), several Oracle DB environments, MSSQL, ADS, TS and more. These are memory-hungry applications, and the total memory allocated there (usually memory is the immediate bottleneck, followed by disk IO performance) is about 150GB ram, in total, with shared storage and the entire shabang. Other customers of mine use smaller environments, running one or two servers, with several tenths of vms on them. They were unable to reach anywhere near this capacity (amount of VMs, performance of every single VM) using VMware Server, of course. Make your own pick. I can only recommend to use the enterprise class tools, especially if they can come for free, and/or you could buy support.

Re: Hebrew search in PDFs is backwards?
Diego, thanks for taking the time to check this out. Appreciate it. I will play around and see what I can do, but I'll only have a chance after exams. I'll also take a look at the Evince/GNOME/Pango situation as well. Dotan - it's not strictly a bug. Diego has pointed out that qt (the underlying library used by KDE and hence Okular) has exactly the function we need - one that can convert logical Hebrew to visual Hebrew. The bug is that this is probably a private function (accessible only from within qt, and not from within applications that are based on qt) - although there's a chance we can still use it. If not we can file a bug report and try get the function made public in the next big qt update. In short - I will play around after exams, and file the relevant bug report when I know what's going on. Thanks guys... this has been quite productive, it will be really nice if we can have open source Hebrew searching in PDFs :)) Gadi Dotan Cohen wrote: 2010/1/19 Diego Iastrubni elc...@kde.org: This is really, really bad from qt/src/gui/painting/qpainter.cpp, inside void QPainter::drawText(const QPointF p, const QString str, int tf, int justificationPadding) I see this code: QStackTextEngine engine(str, d-state-font); engine.option.setTextDirection(d-state-layoutDirection); engine.itemize(); QScriptLine line; line.length = str.length(); engine.shapeLine(line); int nItems = engine.layoutData-items.size(); QVarLengthArrayint visualOrder(nItems); QVarLengthArrayuchar levels(nItems); for (int i = 0; i nItems; ++i) levels[i] = engine.layoutData-items[i].analysis.bidiLevel; QTextEngine::bidiReorder(nItems, levels.data(), visualOrder.data()); Now... it seems like QTextEngine::bidiReorder() does exactly what you want logical-visual.

Re: better platform for virtualization
2010/1/20 Etzion Bar-Noy eza...@tournament.org.il: PV drivers were released by Oracle, who run their own virtualization platform based on XenCommunity. Just wondering - are these required to be installed separately when trying to run Windows on CentOS? We generally managed to do that when we tried (got stuck on none of our licenses being accepted). KVM is wasteful and requires VT support even for Linux machines. Not only that, but its virtualized hardware is legacy old hardware supplied by QEMU. The leading virtualization solutions currently in the market are Vmware ESXi, which, for a single server is free and very nice (although you better make sure your hardware is in their support matrix), Microsoft Hyper-V, which is not Linux-friendly, if you care about it, and Citrix XenServer.

I do not have the tools (or wish) to dispute your recommendations above, they sound reasonable and well baked, but if we are about to demonstrate what can be achieved with the options then let me describe what I got running on CentOS 5 (and the old Xen 3.0 which comes with it): 18 physical 2xQuad-core servers with at least 64Gb RAM (some have 80Gb but we decided to stay clear form 8Gb DIMM's) in production. 4 more servers in test env, also with 64Gb RAM each. To do the calculation for you - this is upwards of 1408 Gb of RAM. A total of 70+ virtual guests. ~1.5Tb disk space, on 12 spindles, in each server. That system have been up for over two years now. Only unplanned down time we had were either due to hardware issues or our own mistakes, not the platform's fault. We use DRBD to replicate disks, linux-ha for heartbeat and fail-over, LVS for Virtual IP load balancing. Our up time on the worst part of the system (an old customer portal we are about to replace) is %99.93 in 11 months (5:20 hours of down time since February 2009, that's the beginning of the monitoring data of the current monitoring tools), up time on better parts (properly load balanced) is up to %99.98 since around the same time (1:25 hours down since March 2009). These include system upgrades and migration to new servers. There is a lot to improve but I think it's not bad, considering that our company's entire income depend on these servers staying up. BTW - I just google'd a bit about XenServer centos and found two blog posts: 1. One saying that XenServer actually is a modified CentOS, based on the Vendor: CentOS field in most packages. 2. You must have Windows for the graphic management console, which uses .net.

Re: better platform for virtualization
True indeed. XenCommunity is a fine option, which I have found to be good. I have been running a bunch of servers on it, from a single VM on a physical server (to achieve the management benefits with the very minimalistic loss of Xen) to several tenths of VMs on a server in several farms abroad. I have there about 16 servers in each farm, running several tenths of mission critical VMs. The setup is elegant - any new physical server added to the farm is being automatically installed and defined to be able to run VMs, hands-free. This is something easier to manage when using RHEL/Centos, compared to other products, indeed. Still - the mass use one of the three leading solutions. You would see them in the fortune500, and on many other sites. Notice, again, that KVM is VDI-focused, and as the battle in the server virtualization rages between the leading commercial vendors, the VDI market is somewhat quieter. It's about prestige and ego, but everyone wants to virtualize servers, as desktops are less glorious and require harder work, on most cases. RHEL has made a step towards VDI, with a very clear view of the future, and KVM is their tool.

These are memory-hungry applications, and the total memory allocated there (usually memory is the immediate bottleneck, followed by disk IO performance) is about 150GB ram, in total, with shared storage and the entire shabang. I do not have the tools (or wish) to dispute your recommendations above, they sound reasonable and well baked, but if we are about to demonstrate what can be achieved with the options then let me describe what I got running on CentOS 5 (and the old Xen 3.0 which comes with it): 18 physical 2xQuad-core servers with at least 64Gb RAM (some have 80Gb but we decided to stay clear form 8Gb DIMM's) in production. 4 more servers in test env, also with 64Gb RAM each. To do the calculation for you - this is upwards of 1408 Gb of RAM. A total of 70+ virtual guests. ~1.5Tb disk space, on 12 spindles, in each server. That system have been up for over two years now. Only unplanned down time we had were either due to hardware issues or our own mistakes, not the platform's fault. We use DRBD to replicate disks, linux-ha for heartbeat and fail-over, LVS for Virtual IP load balancing. Our up time on the worst part of the system (an old customer portal we are about to replace) is %99.93 in 11 months (5:20 hours of down time since February 2009, that's the beginning of the monitoring data of the current monitoring tools), up time on better parts (properly load balanced) is up to %99.98 since around the same time (1:25 hours down since March 2009).

RH already included KVM in RHEL 5.4, and will of course continue to include, sell, and support it with RHEL 5.5 and 5.6. Ubuntu has included KVM even earlier. Novell either includes or will include it soon. In fact, a Linux distro would have to work hard to *not* include it, since it's part of the upstream kernel. Xen---isn't and will never be.

Re: better platform for virtualization
Interesting. I am planning to test KVM as soon as we get some time to look at it (it's a technology preview in 5.4, newspeak for beta). My take on the short history of KVM/Kumranet/RedHat is that since Citrix owns Xen, RedHat had to jump ship to another technology to avoid dependency on a competitor. And that's just from business perspective, even before getting into the intricate strengths and weaknesses of each option. Therefore I still expect that RH will have to make KVM work for a server - are you saying that they won't? Then where does this leave KVM value proposition? I keep finding Desktop Virtualization to be a bit of an artificial market - the era of the PC is over soon, the Smartphone is the new PC and the significance of the desktop OS is diminishing every year with all the on-line options (thanks also to Linux and Mac OS X inroads), so the claim that KVM is just for VDI doesn't convince me, as far as I follow you. I just googled kvm vs xen and found an article like http://bit.ly/kvm-vs-xen, circa September 2008 so maybe out of date, but it basically claims that KVM benchmarks are not convincing and that it's faster and leaner because it's not as secure as Xen. Does anyone have a take on this claim? Cheers, --Amos 2010/1/20 Etzion Bar-Noy eza...@tournament.org.il: True indeed. XenCommunity is a fine option, which I have found to be good.
