Yeah, "Could not resolve host: mirrorlist.centos.org" suggests that there's no DNS (and no networking at all) inside your VM. I'm no expert in vmplayer, but have you defined a VM with networking there? What is the output of `ifconfig -a` within your VM? Does a simple `ping 8.8.8.8` work?

Please make sure your network works (you can access the internet). This error has nothing to do with ovirt. Furthermore, why do you want to install vdsm inside a vm? For most purposes it won't work anyway or you get bad performance because nested virtualization (virtualization in virtualization) is very slow. It is just sufficient for demo purposes (in this case you would want ovirt all in one installation).

Re: [ovirt-users] yum update command is failed
Hi, I forgot to indicate I would like to install oVrit Vdsm but I can't do it because the problems have been reported in previous mail. Regards, Ilan.

[ovirt-users] yum update command is failed
Hi, My name's Ilan and I'm a new user. I installed CentOS 7 64 bit with VMware Player as guest and try 'yum update' to get newest application and get error as mentioned below. It seem me the installation determines the IP address as loopback and I don't know how enable it as real/virtual. I copy & paste the findings from Linux and Windows. Any help will be blessed. Regards, Ilan. [root@localhost Desktop]# yum update Loaded plugins: fastestmirror, langpacks Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error" One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64 [root@localhost Desktop]# exit exit [bih016@localhost Desktop]$ ping google.com ping: unknown host google.com [bih016@localhost Desktop]$ ifconfig -a eno1636: flags=4163 mtu 1500 ether 00:0c:29:d9:2b:57 txqueuelen 1000 (Ethernet) RX packets 18 bytes 1080 (1.0 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 0 (Local Loopback) RX packets 386 bytes 33548 (32.7 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 386 bytes 33548 (32.7 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [bih016@localhost Desktop]$ netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface cat /etc/sysconfig/network-scripts/ifcfg-lo DEVICE=lo IPADDR=127.0.0.1 NETMASK=255.0.0.0 NETWORK=127.0.0.0 # If you're having problems with gated making 127.0.0.0/8 a martian, # you can change this to something else (255.255.255.255, for example) BROADCAST=127.255.255.255 ONBOOT=yes NAME=loopback route -n Kernel IP routing table Destination Gateway Genmask Flags Metric RefUse Iface cat /etc/*-release CentOS Linux release 7.0.1406 (Core) NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/"; BUG_REPORT_URL="https://bugs.centos.org/"; CentOS Linux release 7.0.1406 (Core) CentOS Linux release 7.0.1406 (Core) uname -a Linux localhost.localdomain 3.10.0-123.el7.x86_64 #1 SMP Mon Jun 30 12:09:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux cat /proc/version Linux version 3.10.0-123.el7.x86_64 (buil...@kbuilder.dev.centos.org) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) ) #1 SMP Mon Jun 30 12:09:22 UTC 2014 C:\Users\PC User>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : PCUser-PC Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : localdomain Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller Physical Address. . . . . . . . . : EC-A8-6B-FA-3D-15 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::91aa:14b3:7d79:9b8b%11(Preferred) IPv4 Address. . . . . . . . . . . : 10.0.0.3(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : יום שלישי 09 דצמבר 2014 14:15:01 Lease Expires . . . . . . . . . . : יום שלישי 09 דצמבר 2014 15:15:01 Default Gateway . . . . . . . . .
