Comments (0) Back in the 60 and 70s, there are so many musical groups with real music for real people, the following are some of the them I love the most!
Puff the Magic Dragon by Peter, Paul and Mary
California Dreaming by The Mamas & The Papas
Sound Of Silence – Simon & Garfunkel
Although I am not particularly like Country Music, but this song is the one that moves me, and it’s also the one Leslie Cheung performed in year 2000 CRHK IDClub Concert, Good Taste, GorGor!
It’s like a totally new re-discovery for me. I just came to know about Roberta Flack only yesterday after going through the list of Grammy’s Best Song of the Year, and surprisingly found she was the original singer of “The First Time Ever I Saw Your Face” (1973) and “Killing Me Softly” (1974)
The First Time Ever I Saw Your Face (1973), it’s such a Beautiful song!
Killing Me Softly (1974), definitely a classic! Roberta said she wrote this song after seeing Don McLean of American Pie fame in concert.
Enjoy!
I accidentally discovered the following on Wiki today, simply copy and paste the song into Youtube, then you had your magically Pandora Box.
Grammy Award for Song of the Year
Grammy Award for Record of the Year
I just can’t stop loving the great music from the 60 and 70s, and those are the real music for real people.
Btw, I came to know Roberta Flack only by today and found out she’s also the original writer and singer for Killing Me Softly (1973)
Enjoy!
It seemed the market for 3rd party virtualization tools is really heating up, this time it’s VKernel offers some free apps for those who love every bites of those nice looking GUI based tools.
I’ve tried them all, well, it does what it suppose to, which is just to give you a very preliminary of what your current virtual infrastructure is and also present you some problems it discovered, to get into more details, you have to pay as expected. Well, to some extend, I don’t like VKernel’s free tools, as they are really does nothing but to get you into buying their products, by contract, Veeam is doing much better for the free products that’s actually useful, so I’ve uninstalled all 4 after 30 mins of testing as I found they are really not useful at all.
A few years back, I was seriously consider buying VMkernel’s chargeback product as it’s more advanced than VMware’s chargeback product, but both contains flaw and drawbacks. After almost 3 years, I still don’t see anyone on the market offers a good cloud based chargeback/billing panel for easy to use and customize to individual company’s requirement, if you know any new comer, please drop me a line, thanks.
Mix Greens from Australia, Cherry Tomatoes from Israel, Organic Cucumber from Local, Feta Cheese from Greek, and a touch of Extra Virgin Olive Oil and Balsamic from Italy. Together with a slice of home baked bread and some left over Carbonara, this makes a perfect lunch!
The cost for the salad per serve is about HK$25, way cheaper and healthier than buying the ready-made ones from super market, this price of course not counting the labor that is. 
I’ve read the Wiki page for installing OVF on ESX and failed once already because I bridged the vNICs on the same vSwitch without using VLAN, so eventually I crashed my network as looping started to occur.
So this is my second attemp, please refer to the picture I’ve attached, hope you can give me some advice and suggestions.
1. So basically, I have ONE vSwitch with TWO physical NICs binded together to have Load balancing and failover.
2. Within, I have THREE Port Groups:
- External (no VLAN) connects to Internet
- Untangle DMZ (VLAN 21) – Useless as I will use Transparent Mode
- Untangle Internal (VLAN 22) – where I put VMs that I want to protect behind the Untangle.
Is the following concept correct?
1. When I use Untangle in Bridge or Transparent Mode, I will ONLY utlilize two interfaces External (no VLAN) and Untangle Internal (VLAN 22), so these are the two vNICs Untangle VM will connect to. This leaves Untangle DMZ useless, so I can remove it from VMX or VM configuraiton GUI?
2. I Understand I need to enable Promiscuous Mode in order to have Untangle to scan the network in transparent mode (ie, a sniffer that is), (side topic: Do I need to have Promiscuous Mode if I am using Route Mode?)
I understand I need to enable Promiscuous Mode on Virtual Switch Level (ie, toppest level), which I DON’T WANT to due to security reasons (ie, VM behind Untangle can sniff the whole network right?), Can I enable Promiscuous Mode in individual Port Group Instead?
If Yes, the ONLY Port Group need to have Promiscuous Mode enabled is Untangle Internal (VLAN 22) right? Where it is the Port Group all the VMs are going to connect to. I do not need to enable Promiscuous Mode in External (No VLAN), is this correct?
Or I HAVE TO ENABLE IT on vSwitch level? but why? I thought individual Port Group will OVERWRITE the default setting, NO?
But wait, no matter where I enabled the Promiscuous Mode (ie, vSwitch level or Port Group level), the risk is still here, can I say I am allowing all the VM to have the capability to sniff traffic on the network? If yes, this is absolutely NO GOOD in using Untangle as enabling Promiscuous Mode will open a big security hole in L2 (ie, enabling Promiscuous Mode will render my switch to a hub)
3. FYI, the TWO PHYSICAL NICs (ie, vmnic8 and vmnic0) are connected to the same physcial L2 switch. VLAN 21 AND VLAN22 have been configured on this physical switch as well, also VMware VST VLAN tagging is used on the Port Group. I wonder if my current configuration will STILL create a loop that will crash my network again? (I don’t see how it can, but really want to double make sure and confirm with you guys)
4. Where is the management interface for Untangle going to be in this case? Do I need to create a new port group say Untangle – Management VLAN 23, and also add a new vNIC (probably just use the one for DMZ) and then connect to this Untangle – Management port group.

Now I understood Port Group with VLAN VST Mode won’t work with Untangle and confirmed again with what’s on the Wiki, the document said it clearly “Each vSwitch should be connected to it’s own Physical NIC, or at least be separated by VLAN tagging at the physical NIC level. ” (ie, on the Physical NIC level and the picture attached above also confirmed this).
So does this mean Promiscuous Mode for bridge mode can ONLY work on Virtual Switch Level, but not Port Group Level?
Um…it’s quite disapointed as I gradually found out Untangle on ESX has so many limitation (ie, no VLAN tagging, must enable Promiscuous Mode for vNic connecting VMs, must have Promiscuous Mode on vSwitch but not on Port Group).
So I have decided to use Route Mode now to aovid the above limitation now.
Since I don’t have any more physical NIC to spare, can I create an internal vSwitch (ie, WITHOUT NIC) for Untangle VM ?
ie, External > Untangle External > Untangle Internal (which is on the internal vSwitch without NIC) and all the VM will be on this same internal vSwitch, which will be all protected by Untangle that is.
This will work right? Anyone Please?

Finally, I’ve got Untangle 8.1 OVF working under ESX 4.1 in route mode, the solution is very simple:
1. Simply remove the last NIC in VM configuration, this will get rid of the DMZ NIC, leaving only External and Internal NICs. These two NICs are exactly what Route Mode requires.
2. Assign External NIC to your external connectivity to the Internet, and Internal to a seperate Port Group (in my case it’s VLAN 20 – Untangle)
3. Reboot Untangle, now, you won’t be able to use the default admin/passwd to login, it’s ok, just reset it, after successfully login to the console, configure the statics IP for both External and Internal.
That’s all you need, simple and neat! and I am really starting to fall in love with Untangle’s GUI, they do look so much cooler than my dull Netscreen’s GUI.
號稱全球第一部的香港3D三級片﹐鋪天蓋地式地宣傳的確令吸引力大增﹐看完後﹐覺得3D效果很不給力﹐最後才知道原來肉蒲團是套警世的愛情片。

Yesterday, I tried the cpuid.coresPerSocket setting on a testing W2K3 Web Edition VM (plain install, no SP), I set cpuid.coresPerSocket = 4 with 8 vCPUs and I was able to boost the VM to 8 CPUs in task manager (ie, 2 sockets with 4 cores on each sockets), then I remove the cpuid.coresPerSocket parameter from .vmx and reduce the vCPU to 1, problem started to occur after reboot the VM.
Veeam Monitor and ESX Performance Tab started to show CPU over usage alarm and CPU stayed at 100% no matter what, I even remove the VM from Inventory as added it back again as I though it may solved the problem, nothing worked until I found VMware KB1077.
However there is no option in Device Manager > Upgrade Computer HAL to change from Multiprocess HAL to Uniprocessor HAL prior W2K3 SP2, I do have a little program to do it, but I forgot where I put it, so I simply upgrade the VM to SP2 and all the problem disappear after reboot.
I don’t think this will occur in W2K8, probably only happen in old OS like W2K, W2K3 prior SP2, so all you need to do is to select the correct processor HAL for your VM.
