As a purpose of testing, I am trying to spin up instances of large size, I mean of 8 vCPU’s and greater than 20 GB memory, with 50 GB storage. Physical host has 48 GB RAM and 16 CPU. But everytime receives the same error
Failed to perform requested operation on instance "TestBigVM", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].
In nova compute log, this is the last entry, and can’t see any errors:
2019-01-20 22:39:46.447 16511 INFO nova.compute.resource_tracker [req-ded356b5-7a71-451d-a834-db9e696b07dd - - - - -] Final resource view: name=openstack.xxyyzz.com phys_ram=49139MB used_ram=512MB phys_disk=49GB used_disk=0GB total_vcpus=16 used_vcpus=0 pci_stats=
Have googled so many links like https://ask.openstack.org/en/question/54326/cant-create-instance-no-valid-host-was-found-nova-compute-is-not-running/ and then also tried virt_type=kvm or qemu, but everything failed.
Is there any alternative or legitimate solution for this.? Stuck in between some task and this is very critical for the assigned task. Any help would really be appreciated.
So today I decided to register a new domain. I like the nickname I'm using on this forum (and some others) and decided to register it so I could set up a blog so I went to Godaddy and there I found that the domain is already taken. I went to see it live and saw that jblogger.com is a site about Java programming, so my dream of setting up a blog at jblogger.com is gone.
My perfect domain is already taken so what should I do now? Go and settle with…

What official spells exist that can be used by characters to resurrect their fallen comrades in Dungeons & Dragons? Which classes can cast them and at what level?
So I want to see a list with all available driver packages within Windows 10. These drivers auto-install once you plug in the device.
I have found a tool that sees the currently installed drivers (https://github.com/lostindark/DriverStoreExplorer). But that is not what I am looking for.
The reason I want to see this list is that I personally dislike installing drivers from printer manufacturers and thus was wondering which printers auto-install their drivers using Windows when you plug them in. If I could get a list with all drivers available for auto-install I could choose my printer based on this list.
My DM has taken us into the Feywild, into an elven city that should be complete with shops, trading post and the like. We’re heavy with gold and I’d like to take the opportunity to obtain items I couldn’t ordinarily come by.
I know the DM could create this opportunity but the thing is, he’s not too imaginative about such things. On the other hand, he’s generally really open to players’ suggestions for fleshing out the environment — but he strongly prefers our requests to make reference to published materials.
So are there any such items that could be available, that can be backed up with any good references? Maybe in other published adventures?

there are guides on rooting and it first requires to unlock bootloader on nokia3, at first i did do it but due to some issue i had flash firmware ,after flashing back there was a option available of oem unlocking . So do i have to unlock bootloader even if i had oem unlocking option available in settings and also can you tell on starting device i get red state warning is it a big issue or should i ignore it.
I’m currently building an e-learning course that has 2 parts to the course. The user needs to finish part 1 before part two “unlocks”.
I currently have this section grayed out, with microcopy that says “complete part one to unlock this section”,
Is there an alternative way to do this that I’m not thinking of?
My apologies if question is not in correct format. I don’t post here often. I don’t know what tags would be appropriate for this question, or even if this is an appropriate question.
Looking for algorithm for closest available resource.
n people P1-Pn, n taxis T1-Tn, are in a 2 dimensional coordinate system eg x,y
Determine Person Taxi pairs if each person walks to the closest taxi that will be available to them, and not taken by another person. Ties of two (or more) people to same taxi can go to the person of lower index. Ties of two (or more) taxis as closest taxi can go to taxi of lowest index.
Does this go by a common problem name? What algorithms exist?
As for what algorithms exist, I can think of 2 right off but I doubt they be considered efficient. 1. use recursion, eg find closest person taxi pair, remove both from available list, and run again. 2. enumerate (n squared) all possible P-T pairs into binary tree sorted by distance value, and then traverse binary tree starting with lowest value until each P has unique T. 3. or can someone offer better algorithms?
