Hi, I have a problem with the SLIRP's DNS server. I built from sources QEMU v 0.13 on Linux debian 2.6.26-2-686 with gcc version 4.3.2 (Debian 4.3.2-1.1).
When I don't pass any network options to QEMU, then I should get a user networking with SLIRP. According to the man page, QEMU should create a private network 10.0.2.0/24, and run a DHCP server on 10.0.2.2, and a DNS server on 10.0.2.3. And indeed such a network is created, the DHCP server assigns the 10.0.2.15 IP address, but in the DHCP transaction it seems there is no DNS server mentioned, and my system complains about a missing DNS server. Let me describe how I got this problem. I start the CentOS installer this way: qemu -cdrom CentOS-5.5-i386-netinstall.iso The installer runs, asks questions, and something goes wrong. On the third console (Alt + F3 in the virtual machine), I can read errors: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 6 DHCPOFFER from 10.0.2.2 DHCPREQUEST on eth0 to 255.255.255.255 port 67 DHCPACK from 10.0.2.2 bound to 10.0.2.15 -- renewal in 33026 seconds. DHCPv4 eth0 - obtained lease 10.0.2.15 DHCPv4 eth0 - option subnet-mask: 255.255.255.0 DHCPv4 eth0 - option subnet-mask: - prefix_len: 24 broadcast: 10.0.2.255 DHCPv4 eth0 - option routers: no DNS servers, can't look up hostname The installer complains that a DNS server is missing, but it seems that the DHCP also doesn't provide a default gateway. I would appreciate it if someone could help me in resolving this problem. Thanks, Irek http://irkos.org
